脑脊液C4A水平在首发精神病发展为精神分裂症的患者中升高。研究设计概述。b在发现队列(KaSP)中，首发精神病(FEP)患者发展为精神分裂症(FEP- scz;n = 29)的脑脊液(CSF) C4A浓度明显高于健康对照组(hc;n = 20)或未发生SCZ的FEP患者(FEP- nscz;n = 15) (hc: 0.28 fmol/ul;95%可信区间[CI] = 0.24-0.33, FEP-nSCZ: 0.29 fmol/ul;Ci = 0.22-0.35, fep-scz: 0.41;CI = 0.34-0.45，调整后P [FEP-SCZ vs. hc]=0.025，调整后P [FEP-SCZ vs. FEP-nSCZ]=0.037)。c各组CSF C4B浓度相似(hc [n = 20]: 0.43 fmol/ul; CI = 0.36–0.57, FEP-nSCZ [n = 15]: 0.38 fmol/ul; CI = 0.30–0.49, FEP-SCZ [n = 28]: 0.46 fmol/ul; CI = 0.44–0.58, adjusted P [FEP-SCZ vs. HCs]=0.550, adjusted P [FEP-SCZ vs. FEP-nSCZ]=0.098). d In the replication cohort (GRIP), patients with FEP-SCZ (n = 17) displayed significantly higher CSF C4A concentrations as compared to HCs (n = 21) or patients with FEP-nSCZ (n = 13) (HC: 0.34 fmol/ul; CI: 0.31–0.47, FEP-nSCZ: 0.28 fmol/ul; CI: 0.25–0.33, FEP-SCZ: 0.50 fmol/ul; CI: 0.41-0.56, adjusted P [FEP-SCZ vs. HCs]= 0.047, adjusted P [FEP-SCZ vs. FEP-nSCZ]=0.001), while (e) CSF C4B concentration were similar across groups (HCs [n = 21]: 0.51 fmol/ul; CI = 0.44–0.63, FEP-nSCZ [n = 14]: 0.56 fmol/ul; CI = 0.47–0.72, FEP-SCZ [n = 17]: 0.55 fmol/ul; CI = 0.41–0.65, adjusted P [FEP-SCZ vs. HCs]=0.999, adjusted P [FEP-SCZ vs. FEP-nSCZ]=0.708). Bar graphs represent medians and error bars represent 95% CIs. Data were analyzed using Kruskal–Wallis H tests followed by post-hoc tests. Significance was set to P < 0.05. All reported p-values are two-sided. Figure 1a was created with BioRender.com. Source data for graphs in Fig. 1b–e are provided in the Source Data file.
