The examination of the predictors of longer-term mortality > 30 days after COVID-19 presentation found consistency in risk factors between regions for older age, longer dialysis vintage, lower hemoglobin levels historically, more inflammation (higher % of neutrophils and lower % of lymphocytes historically), poorer nutrition (lower albumin and creatinine historically), and higher ferritin levels being in the top 15 predictors (Fig. 6 & 9, Additional File 1; Supplementary Table 5). Here, ALB is linked to COVID-19.
