WebApr 11, 2024 · The ORR and DCR were presented with point estimate and its 95% confidence intervals (CI) calculated using the Clopper-Pearson method. Time to event endpoints including PFS and OS were analyzed by using Kaplan–Meier method, with a 95% CI estimated on the basis of the Brookmeyer Crowley method. Webof Brookmeyer and Crowley (1982). This interval can be read directly from the lower and upper pointwise confidence limits for the survival distribution, just as ~P can be read from the Kaplan-Meier curve.
