In addition, 5 immunophenotypes showing negative correlations with prostatitis, including SSC − A on NKT (IVW beta = −0.078, P = .003, 95% CI: 0.878–0.973), HLA DR on DC (IVW beta = −0.091, P = .004, 95% CI: 0.858–0.971), CD14− CD16+ monocyte absolute count (IVW beta = −0.115, P = .002, 95% CI: 0.829–0.958), HLA DR+ CD4+ %T cell (IVW beta = −0.147, P = .008, 95% CI: 0.774–0.963) and HLA DR+ CD4+ % lymphocyte(IVW beta = −0.200, P = .006, 95% CI: 0.710–0.944). The gene discussed is CD4; the disease is male reproductive organ cancer.
