1

Reference Standard 1: al least “slightly improved” = recovered;

2

Reference Standard 2: at least “much improved” = recovered, “slightly improved” = non-recovered;

3

Reference Standard 3: at least “much improved” = recovered, “slightly improved” and “same” = recovered if average pain at follow-up ≤2.

4

Reference Standard 4: at least “much improved” = recovered, “slightly improved” and “same” = recovered if Roland Morris at follow-up ≤3

5

Reference Standard 5: at least “much improved” = recovered, “slightly improved” and “same” = recovered if average pain ≤2 and RM ≤3 at follow-up.
