1. The data was presented as Mean ± SE; 2. the confounding factors of age, years of education, BPRS scores were controlled by Covariance analysis; 3. CSS: clinically stable patients with schizophrenia; FES: first-episode patients with schizophrenia; HC: healthy controls; 4. TMT: trail making A test; SC: symbol coding; HVLT: Hopkins verbal learning test; SS: spatial span; DS: digital sequence; NAB: maze; BVMT: brief visuospatial memory test; CF: category fluency; EIT: emotion intelligence test; CPT: Continuous performance test; MCCB: MCCB total T score.

^⁎All indicated p values were after covariates controlling (age, education, and BPRS scores) and Bonferroni's correction.
