Core Outcome Measures in Effectiveness Trials

Core Outcome Set for GROwth restriction: deVeloping Endpoints (COSGROVE)

General Information

Developing a COS for use in all studies of the prevention and treatment of fetal growth restriction (FGR) is timely and important. Interventions for preventing and treating FGR have been studied in many trials, but evidence is often difficult to synthesise and compare because of differences in the selection and definition of outcomes. To enable future trials to measure similar, meaningful outcomes, we are developing two core outcome sets (COS); one for prevention and the other for treatment of FGR.
