    Y-BOCS scores in the 3 COMT genotype groups. Kruskal–Wallis showed a significant between-group difference in mean Y-BOCS scores (P=0.012). Y-BOCS scores in the Val/Val group were significantly higher

    Y-BOCS scores in the 3 COMT genotype groups. Kruskal–Wallis showed a significant between-group difference in mean Y-BOCS scores (P=0.012). Y-BOCS scores in the Val/Val group were significantly higher than those in the Met/Met group (P=0.01). Also, Y-BOCS scores in the Val/Met group were significantly higher than those with Met/Met genotype (P=0.034). There was a trend for a difference in Y-BOCS scores between the Val/Val and the Val/Met group (P=0.065).

 This study was presented in part at the Meeting of the Society of Biological Psychiatry, May 18–21, 2005, Atlanta, GA, USA, and at the Biennial Winter Workshop on Schizophrenia Research, 4th–10th February 2006, Davos, Switzerland.
