How to report a hazard ratio
WebThe log hazard ratio (experimental relative to control) is estimated by (O – E)/V, which has standard error 1/√V, where O is the observed number of events on the experimental intervention, E is the logrank expected number of events on the experimental intervention, O – E is the log-rank statistic and V is the variance of the log-rank statistic.
