  1. Group I, the patients with mild-to-moderate ASD; group II, the patients with severe ASD. Data are presented as mean ± SEM (minimum valuemaximum value). * The data below the detectable limit were equated zero. The results were analyzed using nonparametric Mann–Whitney U test. **p1, in comparison with healthy controls; ***p2, in comparison with group I
