Abstract
Purpose: Inadequate reporting of nutrition data can hinder the success of nutrition health policies. CONSORT provides guidance for reporting of randomised controlled trials (RCTs) and is required by most journals today, yet reporting of nutrition interventions may benefit from a more tailored approach. A Federation of European Nutrition Societies working group was created to improve quality and completeness of reporting of nutrition trials, and our work to date features a proposal for a CONSORT extension specific to nutrition RCTs. The present manuscript describes a Delphi survey conducted to gather opinion from a wider panel of nutrition and health experts and related interest-holders on our proposal. Methods: We invited 138 potentially eligible participants to take part in the Delphi survey from a representative spread of expertise and geography. We employed a Likert scale with comments for our 32-item proposal in round 1, and a dichotomous scale with comments for our 29-item proposal in round 2. Threshold for agreement was set at ≥ 80% for both rounds. Results: Forty-seven potentially eligible participants responded to our invitation, 38 completed the first round and 36 completed the second. N = 23 (72%) items achieved ≥ 80% in round 1, and 100% of items in round 2. Three items were dropped or merged following round 1. A third Delphi round was not required to obtain consensus. Conclusions: This Delphi expert consensus proposes a 29-item checklist specific to the reporting of nutrition RCTs and will inform further development of guidance through forthcoming consensus meetings.
