Description: Interpretation of Time-to-event Outcomes in Randomized Trials: an online randomized experiment https://academic.oup.com/annonc/advance-article/doi/10.1093/annonc/mdy462/5134288 We performed a randomized experiment. We selected 15 cancer RCTs with statistically significant treatment effects for the primary outcome. We masked each abstract and created 3 versions reporting either the HR, RMSTD, or HR+RMSTD. We randomized corresponding authors of RCTs and medical residents and fellows to one of 15 abstracts and one of 3 versions. We asked how beneficial the experimental treatment was (0 to 10 Likert scale). All participants answered a multiple-choice question about interpretation of the HR. Participants were unaware of the study purpose.
