From: Circulating Vitamin D levels status and clinical prognostic indices in COVID-19 patients
We detected an inverse correlation between VitD levels and CD4/CD8, Neutrophil cell count, NLR and dNLR. Contrarily, a direct correlation was detected comparing VitD levels and CD8 + cell count. The correlation between VitD levels and other parameters was assessed using Spearman’s correlation test
