The p value is the risk of obtaining the observed result, or a more extreme result, by chance if the null hypothesis were true.
There is nothing magical about 0. Otherwise the risk is that they go through their entire career mistakenly looking for the magical 0.
I am running a Vaccine effectiveness study and wanted to calculate the Vaccine effectiveness from OR. The OR is 27 CI This translates to VE of 73 calculated as 1-OR.
Do the confidence intervals also get changed to ? Thanks for your response. I am reading a paper comparing the effects of declawing of cats on various adverse out comes as compared with non declawed cats.
Examples include the following 1. It would have been good if the etymology of terms were added. I am a PhD student in Health Promotion field, currently working on a systematic review of prognostic factors influencing recovery from proximal humerus shoulder in adults.
I do not have a strong background in statistics and a in a trouble to analyze data re: identified predictors from 15 included studies.
As you know, studies have different scale and it is hard for me to summarize the figures in a consistent way.
Do you have any suggestion for me? Hi Azar, Just in case Tim does not see your message, I have a suggestion for where you may want to start your search.
Has your supervisor been able to point you towards any suitable resources? That is great, how I wish you keep sending me such tutorials in ppt or pdf formats.
I have been inspired as such I would wish to learn more from you. I am a health professional as well eyeeing to become the health systems specialist one day.
I have just liked everything in short. Doing a PhD in health science with a qualitative background is proving much harder than initially anticipated!
This summary makes everything seem much more manageable :D. Good luck with the PhD and point your friends towards the blog too if you think they may need it!
Hi Tim, Thank you very much for this article! This is what I have been looking for. Thank you for making it so simple that without a mathematical background I could understand and interpret Odd ratios and CI now.
It was extremely helpful. Please can you help me interpret this odd ratio for a cross-sectional study? Or is the interpretation for odd ratios in a cross sectional study same as those in randomized controlled trials?
Thank you Tim. Could you please explain better? Thank you so much. This blog introduces you to standardised mortality ratios.
What are they, why are they used, how do you calculate them and what are their advantages and limitations. This article explores circadian rhythm, the prevalence of its disruption in modern society, and its affects on cancer.
What are the key steps in EBM? Who are S4BE? Prior to studying Medicine I was a physiologist working in cardiology and also completed a masters in clinical trials.
My Key interests are cardiology, the design conduct and analysis of clinical trials and e-learning. Please feel free to contact me with any feedback, suggestions or requests.

Regards Tim 20th January at pm Reply to Tim. Regards Tim 6th March at am Reply to Tim. Tim Hello Rupy, I think your quote comes from the study: A Phase III trial comparing anastrozole 1 and 10 milligrams , a potent and selective aromatase inhibitor, with megestrol acetate in postmenopausal women with advanced breast carcinoma.
Thank you for your question, I quite enjoyed looking up this paper. Tim P. I just have a question regarding hazard ratios.
Are these similar to odds ratio? Rupy 16th March at pm Reply to rupy. The interpretation of a hazard ratio is essentially the same as an odds ratio. Kind regards Tim 24th March at pm Reply to Tim.
Harry The sentence in my paper was : The most active quartile of women had a similar risk of breast cancer as the least active odds ratio [OR], 1.
I was unsure whether I had interpreted this correctly. Murphy Tim, thanks for the great, concise tutorial.
TIA 25th March at pm Reply to please. Tim Hello, Could you possibly give me a bit more detail and send me a link to where it comes from so I can see it in context.
Thanks Tim 27th March at pm Reply to Tim. Andrea Thanks for your example above. Tim Hello Andrea, The odds ratio is calculated by dividing the odds in the intervention arm by the odds in the control arm.
So the OR is 0. Kind regards Tim 14th April at pm Reply to Tim. Sally Hi Tim, I am studying for a health technology exam… need to learn the formula for calculating a confidence interval but there seems to be a number of different formulas around and am a little confused.
Thanks 17th April at pm Reply to Sally. Tim 22nd April at pm Reply to Tim. Gemma very helpful!!! Judith Hi, thank you very much for your help. Thank you very much for your help 27th April at am Reply to Judith.
Tim Hi Kate, I think this is the study: The effect of desmopressin on bleeding time and platelet aggregation in healthy volunteers administered ticagrelor.
For example if a placebo controlled randomised controlled trial evaluated the effect of a new medication to reduce blood pressure, the results might show: Intervention arm mean reduction in BP 10mmHg Placebo arm mean reduction in BP 2mmHg So the intervention arm has a reduced mean BP of -8mmHg compared to the placebo arm.
Having now established the point estimate we can think about the confidence interval. I hope this example makes sense? The second example in your question can be interpreted in the same way.
Regards Tim 21st May at pm Reply to Tim. If anyone has any further comments on this i would be delighted to read them. Many thanks Tim 23rd May at pm Reply to Tim.
Shemsu Gabiso please I need to know what adjusted odds ratio,crude odds ratio,bivarate and multi varate analysis, logistic regression are.

Anastasia Iliwho Ashi Thanks Tim for your explanation. Paul H Tim, Thank you for a wonderfully simple and memorable explanation of something I should know but have always struggled to grasp until now!
Graeme Little Thanks so much Tim- long time since I did eco stats in Eubalew Was it, as simple as this?
Thank you, you made it! Sergio Hi Tim, Sorry to bother you, but my problem is with sample sizes to different experiments.
If we know the odds of exposure in cases and controls, we can calculate the OR, that is the ratio between the odds of exposure in diseased and in non-diseased individuals.
Calculating the odds-ratio adjusted standard errors is less trivial—exp ses does not work. Convert Part-to-Part Ratio to Fractions.
Odds ratio in this example is found to be hight Once you have the odds and the implied odds , you need to calculate your equity in the pot and then compare the two to see what the correct play is in each situation.
To calculate the front-end ratio, add up your expected housing expenses and divide it by how much you earn each month before taxes your gross monthly income.
The Football Odds Calculator is a free tool to estimate fair odds for soccer bets. Hi, I'm working on a logistic regression model and would appreciate help on converting the odds ratios.
But you can calculate it using some custom formulas. Interpret the measure of association. Something that never happens will have odds of in favor, and something that always happens will have odds of in favor against , though we never express these cases as odds!
The point estimate of the odds-ratio is 1. A relative risk of 1. Or, you can use the logistic command, which reports exp b odds ratios by default:.
It seems crazy that something that applies directly to Tactics and Operations is in a planning ratio. A relative risk [RR] of 1.
Be careful if you are using sports teams odds or betting odds. In logistic regression, the odds ratio equals the antilogarithm of a coefficient.
Given sample sizes, confidence intervals are also computed. Odds ratio on tilastollinen luku, joka kertoo, kuinka tyypillisesti kaksi tekijää A ja B esiintyvät yhdessä.
Calculate the odds ratio for the tuberculosis data in Table 3. Odds ratios are a common measure of the size of an effect and may be reported in case-control studies, cohort studies, or clinical trials.
Since there are 6 combinations which will total 7, the probability is 36 divide by 6, or 1 in 6 chance of rolling a 7. In fact if you know the Odds ratio for one cell, you can find the odds ratio for all cells.
An odds ratio larger than one means that group one has a larger proportion than group two, if the opposite is true the odds ratio will be smaller than one.
Set P1 equal to 0. Calculate the odds ratio of the above study. Hence it only looks nice if the gap between the two chosen values here 0.
As in other sports, the risk-reward ratio never changes based on the sizes of the bets, so feel free to gamble a nickel or the mint which coined it.
The pooled odds ratio is the combined odds ratio of several studies. Further, that ratio only accounts the raw number of troops.
Therefore, the odds and probability of detection if the animal spends 0 minutes on site is e However, this is also a disadvantage given the variable of interest is properly defined, which is why risk ratios are generally preferred.
If we want to talk about risk reduction we should use the relative risk defined via the risk event odds ratio can easily be misinterpreted , but if we are interested in the increase in non-events in the above example then the reverse relative risk should be reported odds ratio now corresponds closely to relative risk.
The standard error of the log risk ratio is known to be:. For reference, this is the formula used for CI limit calculations in this odds ratio calculator.
Therefore it is important to use the right kind of interval: more on one-tailed vs. A confidence interval is defined by an upper and lower limit for the value of a variable of interest and it aims to aid in assessing the uncertainty associated with a measurement, usually in experimental context.
The wider an interval is, the more uncertainty there is in the odds ratio estimate. Every confidence interval is constructed based on a particular required confidence level, e.
Simple two-sided confidence intervals are symmetrical around the observed odds ratio, but in certain scenarios asymmetrical intervals may be produced complex cases, not supported by our calculator.
In any particular case the true odds ratio may lie anywhere within the interval, or it might not be contained within it, no matter how high the confidence level is.
Raising the confidence level widens the interval, while decreasing it makes it narrower, as you can verify simply by setting a different level in our odds ratio calculator.
Similarly, larger sample sizes result in narrower intervals, since the interval's asymptotic behavior is to be reduced to a single point.
While odds ratio confidence intervals are customarily given in their two-sided form, this can often be misleading if we are interested if a particular value below or above the interval can be excluded at a given significance level.
Therefore, to make directional statements about relative odds based on two-sided intervals, one needs to increase the significance level for the statement.
In such cases it is better to use the appropriate one-sided odds ratio interval instead, to avoid confusion. Our free odds ratio calculator conveniently produce both one-sided intervals for you.
