[Correspondence] Refining the faecal incontinence core outcome set – Authors' reply

We thank Zubing Mei and colleagues for their thoughtful comments. The aim of a core outcome set (COS) is to facilitate the standardisation of outcomes to be measured and reported in clinical trials for a specific condition.1 In the case of this COS, the focus lies on ambulatory patients with faecal incontinence who form the majority of the research population, as shown in the European guidelines.2,3 Although we agree that some outcomes might be more or less relevant to specific subgroups, such as those with minimal mobility and those who depend on caregivers, a single COS cannot cater to all variations without losing its standardising function.
