CRP and psychotic disorder: Youth with subthreshold psychosis had similar levels of CRP compared to youth without psychosis (Hedge’s g = 0.15, 95%CI(−0.04) −0.33, k = 3, N = 4054, I2 = 58%); however, the data were too heterogeneous for clear meta-analytic interpretation (Cullen et al., 2017; Khandaker et al., 2014a; Trotta et al., 2021) (Supplementary Figure 3).
