FCGR1A and schizophrenia: When analysing effects across inflammatory subgroups, all four peripheral immune cell markers CD163, CD64, CD14, FCGR3A and the adhesion molecule ICAM1, were significantly increased in high inflammation schizophrenia compared to low inflammation schizophrenia (59–254%, Welch’s ANOVA/ANOVA/ANCOVA, all F > 4.4, all p ≤ 0.003, all post hocp ≤ 0.004, Fig. 3A–E) and low inflammation controls (49–256%, all post hocp ≤ 0.002).
