In the Hungarian cohort, lectin pathway activity (p=0.8729) and MASP-1/C1-INH complex levels (p=0.9085) did not differ significantly between survivors and deceased patients, while C5b-9 levels were again increased in individuals suffering from a COVID-19 related death (p=0.0186) (Figures 9F–H). This evidence concerns the gene SERPING1 and COVID-19.
