To determine the discriminatory power of plasma CC and CXC chemokines in distinguishing children with confirmed and unconfirmed TB from unlikely TB, we performed ROC analysis of CCL1, CXCL1 and CXCL10 in confirmed and unconfirmed TB vs. unlikely TB children and confirmed vs unconfirmed TB (Fig. 3). Here, CXCL10 is linked to tuberculosis.
