Validation of red cell distribution width as a COVID-19 severity screening tool Multivariate logistic Regression Analysis of 331 COVID-19 patients for clinical signs and outcomes (categorical variables) Graphical Abstract. Validation of red cell distribution width as a COVID-19 severity screening tool Aim: The aim of this study is the predictive validation of red cell distribution width (RDW) in COVID-19 patients. Method: In total, 331 COVID-19 patients were classified as severe and non-severe groups based on the WHO standard criteria. The levels of RDW standard deviation (SD) were evaluated as both continuous and categorical variables. Multivariate statistical analyses were used. Results: RDW-SD ≤43 and ≤47 (fL) thresholds showed high specificity (90.1% to 91.4%) for diagnosing non-severe illness and no risk of death. RDW-SD>47 indicated severe illness and a high mortality risk while 43
