Advanced Ovarian Cancer dataset

Description

This dataset combines the data that were collected in four double-blind randomized clinical trials in advanced ovarian cancer. In these trials, the objective was to examine the efficacy of cyclophosphamide plus cisplatin (CP) versus cyclophosphamide plus adriamycin plus cisplatin (CAP) to treat advanced ovarian cancer. The candidate surrogate endpoint S is progression-free survival time, defined as the time (in years) from randomization to clinical progression of the disease or death. The true endpoint T is survival time, defined as the time (in years) from randomization to death of any cause
