Diagnostic accuracy of pancreatic exocrine insufficiency (PEI) due to elevated fasting breath hydrogen concentration (FBHC) levels. An receiver operator characteristic (ROC) curve for fasting breath hydrogen concentration (FBHC) and PABA excretion rate. The cut-off value for the highest sensitivity with maintaining specificity was 10.7 ppm for diagnosis of PEI (the area under ROC (AUCROC): 0.796, 95% confidence interval: 0.678–0.913, P < 0.001)
