How should trial teams make decisions about the proportions and diversity of the ethnic groups in their trial?

Extract from article:

Background
The benefits of randomised trials are not shared equally, and people from ethnic minority groups are a key constituency under-served by clinical research and clinical care. The STRIDE project aimed to give trialists practical information about how to decide which ethnic groups should be in their trials, and at what proportion.

Methods
We considered trials in six clinical areas: cancer, cardiovascular, diabetes, maternal health, mental health, and smoking cessation. We created a summary for each, including participants–intervention–comparators–outcomes, and data on disease prevalence by ethnicity. These were discussed with panels with clinical expertise, trial and methodology expertise, lived experience, funding, and experience of working with and on behalf of ethnic communities. For each trial, we asked panel members to decide which ethnic groups should have been involved and at what proportion.
