Other cytokine protein levels per cytokine cluster. Protein concentrations normalised to the low cytokine controls for the cytokines IFNγ, IL-10 and IL-12 showed no effect of cytokine cluster groups in the plasma (a) or the serum (b). For TNFα (serum only), significant differences were found between low cytokine control and elevated cytokine schizophrenia groups (p = 0.016), the elevated cytokine control and low cytokine schizophrenia groups (p = 0.015) and between the elevated cytokine control and the elevated cytokine schizophrenia group (p = 0.002) (b). Bars represent the mean ± standard error (*p < 0.05, **p < 0.01)
