CRP and Behcet disease: ROC curve analysis showed that the level of MON [p<0.0001, AUC area = 0.704, 95%CI (0.653,0.754)], hs-CRP [p = 0.010, AUC area = 0.582, 95%CI (0.533, 0.631)], NLR [p<0.0001, AUC area = 0.622, 95%CI (0.571, 0.673)], MON+ hs-CRP [p<0.0001, AUC area = 0.727, 95%CI (0.680, 0.774)], MON+NLR [p<0.0001, AUC area = 0.732, 95%CI (0.684, 0.779)], hs-CRP + NLR [p<0.0001, AUC area = 0.667, 95%CI (0.620, 0.713)], and MON+hs-CRP + NLR [p<0.0001, AUC area = 0.746, 95%CI (0.701, 0.790)] were predictors of BD.
