Red Blood Cell Distribution Width May Be Correlated with D-Dimer Level in Late Stage of COVID-19

This study examines the correlation between Red Cell Distribution Width (RDW) and hematologic and biochemical parameters across acute, subacute, and chronic disease phases. During the acute phase, RDW showed no significant correlation with D-Dimer levels. As the disease progressed, the correlation intensified, becoming mild in the subacute phase (r=0.276, p=0.028) and moderate in the chronic phase (r=0.438, p=0.006).

本研究探讨了红细胞分布宽度（RDW）与急性、亚急性及慢性疾病阶段血液学及生化参数之间的相关性。在急性阶段，RDW与D-二聚体水平之间未见显著相关性。随着疾病的发展，相关性逐渐增强，在亚急性阶段表现为轻度相关（r=0.276，p=0.028），而在慢性阶段则呈现中度相关（r=0.438，p=0.006）。
