Cox regression vs logistic regression Distinction between hazard/rate ratio and odds ratio/risk ratio – Hazard/rate ratio ratio of incidence rates – Odds/risk ratio ratio of proportions By taking into account time, you are taking into account more information than just binary yes/no Gain power/precisionThe odds ratio (OR) is the ratio of odds of an event in one group versus the odds of the event in the other group An RR (or OR) of 10 indicates that there is no difference in risk (or odds) between the groups being compared An RR (or OR) more than 10 indicates an increase in risk (or odds) among the exposed compared to the unexposed Note that the adjusted odds ratio for age is lower than the unadjusted odds ratio from the previous example This is because when other predictor variables increase the odds of the response variable occurring, the adjusted odds ratio for a predictor variable already in the model will always decrease Summary Odds Ratio vs Adjusted Odds Ratio
