a. Comparison of TMPRSS2 and ACE2 expression level between females (N=19) and males (N=12) for all human lung epithelial cells (a) and by each epithelial cell type (b) within the integrated dataset (Supplementary Table 1). Statistical significance levels computed from an unpaired two-samples Wilcoxon test were indicated in the violin plots (NS: non-significant, *: p < 0.05, **: p < 0.01, ***: p < 0.001). c. Proportion of cells expressing ACE2, and co-expressing of TMPRSS2 and ACE2 (%) in each epithelial cell type and sex of the integrated dataset. Statistical significance levels computed from the Fisher’s exact test were indicated in the bar charts (NS: non-significant, ***: p < 0.001).
