CXCL1 and tuberculosis: Similarly, as shown in Fig. 3B, CCL1 (AUC 0.9639, sensitivity 87%, specificity 93%), CXCL1 (AUC 0.777, sensitivity 68%, specificity 68%), CXCL10 (AUC 0.9187, sensitivity 85%, specificity 71%), exhibited significant discriminatory power with high AUC values, sensitivity and specificity in discriminating unconfirmed TB from unlikely TB children.
