CRP and Behcet disease: ROC curve analysis showed that the level of MON [p<0.0001, AUC area = 0.726, 95%CI (0.675, 0.777)], hs-CRP [p<0.0001, AUC area = 0.628, 95%CI (0.575, 0.681)], NLR [p<0.0001, AUC area = 0.639, 95%CI (0.585, 0.693)], MON+ hs-CRP [p<0.0001, AUC area = 0.757, 95%CI (0.710, 0.805)], MON+NLR [p<0.0001, AUC area = 0.756, 95%CI (0.708, 0.803)], hs-CRP + NLR [p<0.0001, AUC area = 0.697, 95%CI (0.648, 0.747)], and MON+hs-CRP + NLR [p<0.0001, AUC area = 0.775, 95%CI (0.729, 0.820)] were predictors of BD-M.
