Landmark survival as an end-point for trials in critically ill patients - comparison of alternative durations of follow-up: an exploratory analysis

Abstract

INTRODUCTION: Interventional ICU trials have followed up patients for variable duration. However, the optimal duration of follow-up for the determination of mortality endpoint in such trials is uncertain. We aimed to determine the most logical and practical mortality end-point in clinical trials of critically ill patients.
