`::::::: OK, I missed the term ``insufficient evidence`` in the abstract.  That wording is fine, but I think that ``no randomized controlled trials`` would be better, since it's more precise.  I agree with Yobol about how to interpret WP:MEDRS.  If we use an interpretation similar to yours for, say, Tramadol, then we would remove all current Tramadol content, because none of it is based on meta-analyses of RCTs.       `
