ENO2 and sarcoidosis: The ROC analysis showed that the AUCs for NSE and ProGRP were 86.7% and 85.5%, respectively (Figure S1; Table S3), and the optimal cutoff value of NSE was 17.0 ng/ml with a sensitivity of 73.5% and a specificity of 90.2%, which were similar to those of ProGRP in the present cohort including a large number of sarcoidosis patients (Table S4).
