WebConfidence intervals about medians will be estimated using the Brookmeyer-Crowley method and about landmark time points will be calculated using Greenwood's formula and based on a log-log transformation applied on the survival function. Binary proportions and associated confidence intervals will be estimated for within cohort objectives. WebRON BROOKMEYER and JOHN CROWLEY* A k-sample median test for censored data is proposed. The test is more sensitive to differences in median sur-vival times than to differences in shape of the survival curves. The asymptotic distribution of the test statistic is derived under both the null and the alternative hy-
