Fig. 6From: Increased serum amyloid A as potential diagnostic marker for lung cancer: a meta-analysis based on nine studiesDiagnostic accuracy of SAA to lung cancer. a The overall Diagnostic Odds Ratio (DOR) of included studies were 27.52 (p = 0642), which indicated that SAA had a ability to discern lung cancer; b The balanced point for sensitivity and specificity (the Q‑value) was 0.8384. The area under the curve (AUC) was 0.9066, indicating that the overall accuracy was impressive. SORC, summary receiver operating characteristic; OR, odds ratiosBack to article page
