The results of indirect ELISA-rMLP15 for MB and PB patient sera. a ELISA-rMLP15 in sera from 10 leprosy MB patients and 14 HC. b Receiver operating characteristic (ROC) curve used to distinguish between positive MB and HC. c ELISA-MLP15 in sera from 14 leprosy PB patients and 14 HC. d Receiver operating characteristic (ROC) curve used to distinguish between positive PB and HC. AUC area under the curve, CI confidence interval, Se sensitivity, Sp specificity, LR likelihood ratio, HC healthy control, PB paucibacillary, and MB multibacillary
