1. n = 133
2. a Data are mean (SD) scores. The scale is 0–1, worst to best.
3. b Baseline scores between patients and population controls. Positive difference indicates better score and negative difference indicates worse score for population controls than for patients. ns, non-significance
4. * P < 0.05, ** P < 0.01, *** P < 0.001
