Diagnostic value of elevated serum carbohydrate antigen 125 level in sarcoidosis

Figure 1 Carbohydrate antigen 125 levels. Sarcoidosis patients had notably higher levels of plasma carbohydrate antigen 125 (^bP < 0.001) in comparison with healthy control subjects. The solid horizontal lines indicate the medians. The boxes indicate the interquartile ranges. The black T-lines indicate the ranges of measurements. CA125: Carbohydrate antigen 125.

Figure 2 Receiver operating characteristic. The curve shows the specificity and sensitivity percentages of carbohydrate antigen 125 in patients and controls. The area under the curve is 0.9833 (95%CI: 0.9717-0.9949). With a cutoff value of 32.33 U/mL, specificity is 90.2% and sensitivity is 96.3%. Positive (sarcoidosis); Negative (control).
