Abstract

The Coalition to Advance Real-World Evidence through Randomized Controlled Trial Emulation (CARE) Initiative seeks to advance understanding of when real-world data (RWD) can generate valid treatment effectiveness estimates by emulating completed oncology randomized controlled trials (RCTs). A prerequisite for meaningful RCT emulation insights is the identification and use of RWD with sufficient fi…
