  1. Note. Data are presented as the mean ± standard deviation. Independent t tests were used for continuous variables, and Welch’s t test was used if the variances were not equal. Chi-square tests for categorical data were performed. The neurocognitive test scores were converted into Z-standardized scores and were compared with one-way analysis of covariance with age as the covariate.
  2. BPRS Brief psychiatric rating scale, CW Color word interference, HAM-A Hamilton rating scale for anxiety, HAM-D Hamilton rating scale for depression, HCs healthy controls, IQ Intelligence quotient, PANSS Positive and Negative Syndrome Scale, SCW Stroop color word test.
