  1. The p values of age, education, BSSI, HAMD, and duration of illness were obtained by two-sample t-test, and p values of gender and medical characteristics were obtained by Chi-squared test. Six participants from the NSS group and six participants from the SS group didn’t complete the MCCB assessments, so the statistical analysis includes data from only 29 NSS participants and 55 SS participants.
