0.002). In the SZ group, the ADC of callosal fibers in the occipital segment was significantly associated with the z‐score of verbal memory and the composite score. The regression for verbal memory identified the ADC of occipital segment as predictive variable accounting for 36.2% of the variance (B = −12.98; F = 9.64; p = 0.006), and the regression for the composite score identified the ADC of occipital segment as predictive variable accounting for 37.4% of the variance (B = −11.91; F = 10.16; p = 0.005).
