Primary outcome
Across both the MRD and RTD, 67 (73%) of the outcomes were rated the same: 48 (52%) outcomes were rated as ‘consensus in’ by both surveys; 6 (7%) outcomes were rated as ‘consensus out’ in both surveys, and 13 (14%) outcomes were rated as ‘neither consensus in nor consensus out’ by both surveys. Thus, 67 (73%) of the outcomes were rated the same across both survey arms. There were differences in the way 25 (27%) outcomes were prioritised between the two survey types. The disparities in 19 (76%) of these 25 outcomes were whether outcomes were rated important (4–6 on the Likert scale), or critical (7–9 on the Likert scale) for inclusion in the COS. For the other six outcomes, the disparities were whether the outcomes were rated as not important (1–3 on the Likert scale) or important (4–6 on the Likert scale). All outcomes that were voted ‘consensus in’ or ‘neither consensus in nor consensus out’ by both or either survey, were carried forward for discussion at our consensus meetings.
