z‐score of the Tower of London test. The regression for the Tower of London test identified the FA of temporal segment as predictive variable accounting for 29.5% of the variance (B = 73.2; F = 7.12; p = 0.016; Figure 3). In the SZ group, the FA of callosal fibers in the posterior parietal segment was significantly associated with the scores of the PANSS positive, PANSS negative, PANSS general psychopathology, and PANSS total. The FA of callosal fibers in the temporal segment was significantly associated with the score of the PANSS negative. The regression for the PANSS positive identified the FA of posterior parietal segment as predictive variable accounting for 39.8% of the variance (B = 275.84; F = 11.26; p = 0.004). The regression for the PANSS negative identified the FA of posterior parietal segment (B = 396.79; p < 0.001) and temporal segment (B = −197.60; p = 0.004) as predictive variable accounting for 65.9% of the variance (F = 15.45; p < 0.001). The regression for the PANSS general psychopathology identified the FA of posterior parietal segment as predictive variable accounting for 52.4% of the variance (B = 567.38; F = 18.72; p < 0.001).
