We would like to ask for your contribution in the MRC funded project that is developing reporting guidelines for randomised controlled trials (RCTs) protocols and reports using surrogate primary endpoints: the SPIRIT-SURROGATE and CONSORT-SURROGATE extensions.
By taking part in the survey, you will help to develop guidelines for reporting RCTs with surrogate primary endpoints. The survey will ask for your views on the most important items that should be reported by RCTs reports and protocols using surrogate endpoints.
