Correlation between ACE2 expression in AMs and clinical factors. (A) Smoking pack-year (n = 36), (B) Age (n = 56), (C) BMI (n = 56), (D) FEV1 (n = 27), (E) measured FEV1/predicted FEV1 (n = 27) and (F) FEV1/FVC (n = 27). ACE2 MFI was log2 transformed. Correlation was determined using Spearman’s correlation test.
