Rather, GAD1 mRNA was expressed at lower and comparable levels in both inflammatory subgroups, 31.88% in the high inflammatory/schizophrenia subgroup and 30.10% in the low inflammatory/schizophrenia subgroup, compared to the control group (F(2,49) = 7.551; p = 0.001, both schizophrenia-control comparisons p < 0.001) (Table 3). Here, GAD1 is linked to schizophrenia.
