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&gt;47 indicated severe illness and a high mortality risk while
43
