Based on GRADE assessment for rating quality of evidence detailed in Guyatt et al.52
See Table A3 for risk of bias assessment.
Few events overall; however, target sample size was met and exceeded to achieve planned power to detect differences in primary outcomes, even after accounting for potential attrition. Authors state that ability to rule out a clinically significant 7% reduction in event-free survival was achieved by randomization.
Few deaths during study observation period, adequately powered to rule out a 10% difference in overall survival (OS) between groups but unclear if time was sufficient to adequately evaluate OS.
