Methodological Summary & Software Environment</b></p><ul><li>Study Screening & Quality Assessment: Literature screening conducted per PRISMA 2020 guidelines; study quality and risk of bias evaluated via the Quality in Prognosis Studies (QUIPS) framework across 6 key domains.</li><li>Meta-Analytic Synthesis: Conducted in R/RStudio (version 4.3.0) utilizing random-effects models (DerSimonian–Laird and Restricted Maximum Likelihood [REML] estimators) implemented primarily through the `meta` and `metafor` packages.</li><li>Effect Metrics: Natural log hazard ratios [ln(HR)] and standard errors [SE(lnHR)] derived from published Cox models, Kaplan–Meier survival curves, or summary survival statistics.</li></ul><p dir="ltr"><b>5.
