CCR2 and post-traumatic stress disorder: Additionally, the OR for FSC‐A on HLA DR+ CD8br in relation to PTSD risk was calculated at 1.048 (95% CI = 1.018–1.079, p = 0.002, FDR = 0.039), and for CCR2 on CD14− CD16+ monocyte, the OR was determined to be 1.059 (95% CI = 1.027–1.092, p = 0.001, FDR = 0.008) (Figure 3, Tables S3 and S4).
