Clinical Pharmacology &Therapeutics, Volume 119, Issue 4, Page 1080-1087, April 2026.External comparator cohort (ECC) studies with real‐world data (RWD) may provide more reliable estimates of treatment differences compared to single‐arm trials (SAT), yet they face limitations such as selection bias and data heterogeneity. This study assessed the perceived strength of evidence of ECC studies compared to SAT and randomized controlled ...
