Score YES	If missing outcome measures were unlikely to bias the results (e.g. the proportion of missing data was similar in the pre‐ and post‐intervention periods or the proportion of missing data was less than the effect size i.e. unlikely to overturn the study result)
Score NO	If missing data was likely to bias the results.
Score UNCLEAR	If not specified in the paper (Do not assume 100% follow up unless stated explicitly).
