ALB and COVID-19: On the other hand, surviving patients with higher COVID-19 severity showed lower monocyte (medians 9.8%, 8.6%, 8.5% and 6.1%, p = 0.019) and lymphocyte proportions (medians 20.1%, 12.8%, 10.1% and 7.9%, p < 0.001), as well as slightly lower levels of albumin (medians 41, 39, 37 and 34 g/L, p < 0.001).
