Scores for depression and nonspecific physical symptoms at baseline and follow-ups after treatment. Median (IQR) differences in scores for depression (a) and nonspecific physical symptoms (NSPhS) (b) in 40 patients with myofascial temporomandibular disorders before (baseline) and after repeated intramuscular tender-point injections with granisetron (GRA-group) or control substance (isotonic saline; CTR-group). Depression-scores are classified as normal (<0.535), moderate (0.535-1.105) and severe (>1.105), and the NSPhS-scores are classified as normal (<0.5), moderate (0.5-1) and severe (>1). There were no significant differences between groups in depression- or in NSPhS-scores at baseline. *Significant difference compared to baseline (Friedman-test with Dunn’s post-hoc test; P < 0.05)
