RDW has also been shown to correlate with measures of inflammation in non-COVID-19 settings, including tumor necrosis factor (TN-F)-α [13] in sepsis, interleukin (IL)-6 [14,15] in heart failure and human immunodeficiency virus infection, and high sensitivity C-Reactive protein (hsCRP) and erythrocyte sedimentation rate (ESR) [16,17] in other populations. Here, TNF is linked to Sepsis.
