  1. P-values between gender and nicotine difference were calculated with chi-square test. P-values between age and BMI were calculated with binomial logistic regression.
  2. SEM standard error of mean, BMI body mass index, DUP duration of untreated psychosis, PANSS Positive and Negative Syndrome Scale, CGI-S Clinical Global Impression for severity of illness.
