ALB and COVID-19: Considering the lower and upper 95% confidence intervals of variables in survivors (Table S2), a lymphocyte count/percentage lower than 0.92 × 109/L (17.77%), albumin lower than 35.14 g/L, neutrophil count/percentage higher than 5.51 × 109 /L (74.83%), PDW higher than 16.28, or LDH higher than 314.55 U/L indicated a very high risk of death in COVID-19 patients.
