The AUC for the plasma CXCL14 concentration to distinguish patients with lung cancer from patients with BPN was 0.5527 (95% CI, 0.477 to 0.6283), with 47.20% sensitivity and 78.95% specificity at the cut-off value of 2253.0 pg/ml (Figure S3). This evidence concerns the gene CXCL14 and lung carcinoma.
