Increase of CD4⁺ T-cell counts during ART was not associated with Tregs percentage at baseline.

Stratification of HIV-infected individuals based on their CD4⁺ T-cell counts at baseline (<200, 200–350, and >350 cells/μl) and on their Tregs percentage at baseline (<10%, grey lines; ≥10%, green lines) and evaluation of the CD4⁺ T-cell reconstitution along ART. Each thin line represents a single individual and bold lines represent the median of all individuals from each group at each specific time point. A two-way ANOVA repeated measurements followed by Sidak's multiple comparison tests was performed to compare the CD4⁺ T-cell evolution of the two groups throughout ART: <200: F (1, 26) = 0.177, P = 0.6774, η²_P = 0.017; 200–350: F (1, 31) = 1.017, P = 0.3211, η²_P = 0.055; and F (1, 13) = 3.911, P = 0.0696, η²_P = 0.419). ART, antiretroviral therapy; M, months.
