( 1 ) recently suggested a method of presenting data that was complementary to Kaplan – Meier curves, with the aim to supplement ordinary survival probability plots with a direct and intuitive indication of the variability in survival times among individual patients. They showed how survival time histograms could be obtained by imputing censored survival times with values predicted by a log-normal model. We agree with Royston et al. ( 1 ) that Kaplan – Meier plots tend to conceal survival time variability, thus obscuring the impact of the treatment. We also agree the actual benefi ts of the treatment depend not only on the hazard ratio but also on theRead More
