SPIRIT/CONSORT-Surrogate

Surrogate outcomes CONSORT and SPIRIT Extension: Development of reporting guidance to improve quality of research used in decision-making

Grant agreement ID: MR/V038400/1  

Principal investigator: Oriana Ciani

Team UB/Cergas: Oriana Ciani

Partners: University of Glasgow, University of Bristol, University of Edinburgh

Sponsor: UK Medical Research Council

Duration: 18 months

Abstract:

This project led to the development of CONSORT (Consolidated Standards of Reporting Trials) and SPIRIT (Standard Protocol Items: Recommendations for Interventional Trials) extensions for randomised trials with a primary surrogate endpoint. These extensions are important. Incomplete, unclear, or inaccurate reporting of trial design, conduct and analysis can hinder interpretability, lead to erroneous conclusions about the long-term safety and efficacy of interventions and impact on decisions relying on those poorly reported research findings.
