Keywords (Tags): clinical characteristics, risk factors

• An elevated level of red blood cell distribution width (RDW, >14.5%) at hospital admission was associated with an increased mortality risk among 1,461 patients diagnosed with SARS-CoV-2 infection in Boston (RR=2.7). In addition, patients whose RDW increased during hospitalization had higher mortality compared with those whose RDW did not change (6% vs 24% among 1,173 patients with normal RDW at admission and 22% vs 40% among 468 patients with an elevated RDW).
