CD8A and Sepsis: The CMV‐DNA–negative conversion and 28‐day mortality of active CMV–infected patients with sepsis could be predicted using cutoff values of 151 (74.5% sensitivity and 87.1% specificity) and 64.5 (52.9% sensitivity and 92.3% specificity) CD8+CD28+ T cells mL−1 at ICU admission, respectively.
