Quantitative trait analyses of PANSS score, antipsychotics dosage and altruism score.

Genetic effects on PANSS positive scores (PANSS Score) of Chinese schizophrenics; average antipsychotics dosage, in mg fluphenazine equivalents per day, of US schizophrenics; and altruism scores of healthy Chinese subjects are shown. The power estimates for the three cohorts were 0.6, 0.4 and 0.8, respectively. The effect sizes were represented by Pearson’s r values, and the p-values were obtained using the linear-by-linear association test in SPSS for additive effect testing. Significant p values (p<0.05) are shown in bold font.
