Frequency of CD4+CD25+FoxP3+ T cells (Tregs) within the total CD4+ population of TB patients throughout treatment. Box plots show median values, 25–75 percentiles of data in each group with maximum and minimum values. HCo: healthy controls. T0: time of diagnosis; T2, T4, T6: 2, 4, and 6 months after starting the specific anti-TB treatment; T9: 3 months after the end treatment completion. versus T0 and T6 ; HCo versus T2 and T4 . ^#T0 versus T2 ; T0 versus T4 ; versus T9 .
