Accelerated vs conventional, disease free survival: both trials reported this, but substantial clinical and statistical heterogeneity (P = 0.0004, I2 = 92%) meant a pooled analysis was not reported (Analysis 1.3).2 studiesGRADE not reported

How reviews are matched to this question

Reviews word the same question differently. Four decision models (TypeSafe's Jev, Liquid AI's d1-ultra, SubQ Snap and Baseten's Elephant) judged each wording of the population, intervention, comparator and outcome against the others; two wordings count as the same when at least three of them agree and none clearly disagrees, and findings count as this question only when all four elements match. Timing, setting and subgroup never split a question: they are shown on each finding.
