Interestingly, the predictors of BD-M patients were consistent with the risk factors of BD patients the levels of MON [p<0.0001, OR = 215.916, 95%CI (29.737, 1567.718)], hs-CRP [p = 0.012, OR = 1.235, 95%CI (1.048, 1.457)], and NLR [p = 0.002, OR = 2.779, 95%CI (1.440, 5.360)] (Table 5). The gene discussed is CRP; the disease is Behcet disease.
