ACE and sarcoidosis: Although ACE levels were significantly higher in sarcoidosis patients than in non-sarcoidosis patients (mean 62.3 U/L (SD = 102.8), median 41 [IQR 25.75–67.5] vs. mean 34.9 U/L (SD = 35.7), median 29 [IQR 19–43], p < 0.0001), they did not allow for distinguishing between the groups due to overlapping confidence intervals.
