Figure 1. Compared to mean zonulin levels in healthy controls (1.4 ± 0.58 ng/ml), zonulin levels were approximately 59% higher in SCZ (3.4 ± 1.3 ng/ml, p<0.05) (1A). LBP levels were significantly (p<0.01) higher in SCZ (41%) compared to healthy controls (1B). The mean IAP levels were lower in SCZ (11.4 ± 3.7 ng/ml, p<0.05) compared to the healthy controls (19 ± 5.8 ng/ml) (1C).
