Fig. 4From: Vitamin D status in hospitalized COVID‑19 patients is associated with disease severity and IL-5 productionHeatmap of Spearman’s correlation between 25(OH)D status and inflammatory markers in serum of COVID-19 patients. The levels of 25(OH)D in the serum negatively correlated with NLR, D-dimer, IL-5, IL-8, and positively linked with IL-10 and CD8 + T cell counts in patients with COVID-19. The Spearman rank correlation test was conducted. A cross represents no statistical significance. NLR, neutrophil-to-lymphocyte ratioBack to article page
