Flow cytometry subpopulations of CD4⁺ (a) and CD8⁺ (b) T lymphocytes, NK cells (c), and monocytes (d) in peripheral blood mononuclear cells (PBMC) from healthy volunteers and patients with T2DM without evidence of infection and patients with TB and TB-T2DM prior to the initiation of the DOTS scheme. The data represent means and standard deviations of the results, and the asterisks indicate significance as follows: *, P < 0.05; **, P < 0.001 (for comparisons between groups using ANOVA and post hoc tests).
