Evolution of peripheral blood lymphocytes with vitamin D supplementation. Time evolution of the proportion and the absolute number of CD3⁺ T cells, CD4⁺ and CD8⁺ T cells, CD19⁺ B cells and CD3^-CD56⁺ NK cells. At 2 and 6 months, the proportion and absolute number of CD3⁺ T cells, CD4⁺ and CD8⁺ T cells and CD3^-CD56⁺ NK cells remained stable, while the CD19⁺ B cell frequency and count significantly decreased at 2 months. Mean ± standard error of the mean (SEM) is shown. *P < 0.05 versus Day 0; Wilcoxon test.
