ACE and sarcoidosis: Nonparametric tests and principal component analysis (PCA) were applied to examine associations among CA, morphological features, serum ACE, and sIL-2R.<h4>Results</h4>The mean CA was 31% greater in sarcoidosis than in controls (368.2 ± 169.3 μm<sup>2</sup> vs. 281.4 ± 90.9 μm<sup>2</sup>; <i>p</i> < 0.001), with higher proportions of large/extra-large AMs (41% vs. 14%; <i>p</i> < 0.001).
