Note: Comparison of AUCs of ESR, serum ADA, serum CA125, and hs-CRP with QFT AUC, . Comparison of AUCs of ascitic ADA with ascitic CA125, . AUC: area under the curve; QFT: Quanti FERON-TB; ESR: erythrocyte sedimentation rate; ADA: adenosine deaminase; CA125: cancer antigen 125; hs-CRP: high-sensitivity C-reactive protein.
