“A Phase 3 Prospective Externally Controlled Cohort Trial”.
This is a remarkable title, as the investigators have re-analyzed the OS data of the study against published external controls and present this as a prospective trial. It is obvious, however, that this is not a prospective analysis but a post hoc retrospective analysis: the investigators had seen the data, both of their own study and of the cohorts taken for comparison and then decided to go ahead with cross-trial comparisons.'
