The study assessed outcomes in 985 COVID-19 patients, focusing on NLR, CD4+, and CD8+ cell counts. Patients with higher NLR or lower CD4+/CD8+ counts had increased mortality. Key findings include higher APACHE II, SOFA, and ICHIKADO scores, longer hospital stays, and a higher need for CPR in these groups.
