Fig. 2

Frequencies of lymphocytes’ subpopulations and CD4/CD8 T cell ratios. The Figure shows the frequencies of CD4 T cells (2A), CD8 T cells (2B), ratio CD4/CD8 (2C), NK cells (2D), NKT cells (2E) and B cells (2F) in the control subjects (n=20), therapeutic success (n=40) and therapeutic failure (n=50) groups. Healthy control subjects and PLHIV-1 under ARV treatment for at least 6 months were recruited at the University hospital of Abomey-Calavi/Sô-Ava between October 2021 and April 2022. Data shown as box plots representing medians (with 25th and 75th percentiles). The statistical differences were determined using the nonparametric Kruskal-Wallis test with Dunn’s multiple comparisons. Differences were considered significant when p values are less than 0.05.
