Question: is this a 2) strong advice, 1) weak advice 0) no advice?

A 17-item HAMD total score of 16, one of our relapse/recurrence criteria, indicates mild depression requiring treatment and has thus been used as an entry criterion in many clinical trials (for example Reimherr et al, 1998; Kalb et al, 2001).
