Comparison of median values of T regulatory cell populations during the study period at different time points between HDR and PDR brachytherapy groups: (a) Treg (CD4⁺CD25⁺FoxP3⁺CD45RA⁺) subpopulation; (b) Treg (CD4⁺CD25⁺FoxP3⁺CD45RA⁻) subpopulation. Significant changes are observed in the HDR group in both Tregs subpopulations at the different endpoints in Figure (a) y (b). In PDR patients, differences only are observed in CD45RA- subpopulation, Figure (b). However, no significant differences are shown in the percentage of Tregs between the HDR-BT and PDR-BT groups
