This calculator allows you to perform a post-hoc statistical evaluation of time to event data when the outcome of interest is the change in the averagehazard ratio (abbr. HR, a.k.a. relative hazard or RH) between an exposed/treatment group and a control group. The tool only has one input field for your raw data and one … See more The hazard ratio quantifies the difference between the hazard of two groups and it is calculated as the ratio between the ratios of observed events and expected events under the null … See more In many medical, epidemiological and economic analyses you can see an average hazard ratio for the difference between two groups … See more The standard error of the loghazard ratio can be approximated with: Accordingly, confidence intervals in our hazard ratio calculator are calculated using the formula: where HR is … See more Despite often being mistaken for being the same thing, relative risk and hazard ratios are nothing alike [3,4]. To give an extreme example, the relative … See more WebSince the hazard is a function of time, the hazard ratio, say, for exposed versus unexposed, is also a function of time; it may be different at different times of follow up. For example, if the exposure is some surgery (vs. no surgery), the hazard ratio of death may take values as follows: Time since baseline Hazard ratio 1 day 9 2 days 3.5 dehya skin color
