MASP1 and COVID-19: Additionally, we noticed differences that did not reach statistical significance after multiple comparison; we detected lower MBL levels in severe than non-severe COVID-19 in Asian individuals (adjusted p-value = 0.08); and amongst individuals of Black ethnicity, levels of M-ficolin and MASP-1 were higher in severe disease (Figure 3A, adjusted p-values 0.06 for M-ficolin and 0.08 for MASP-1).
