The ratio of Treg/Th17 cells in the peripheral blood of PCOS patients. A FCS data for the proportion of Treg cells (CD4 + CD25 + Foxp3 +) in the blood of subjects in two groups. Plot number in quadrant 2 (Q2) represents the percentage of Treg cells in CD4 + T-cells. B FCS data for the proportion of Th17 cells (CD4 + IL17 +) in the blood of subjects in two groups; Plot number in Q2 represents the percentage of Th17 cells in lymphocytes. C Bar plot of the Treg cells/lymphocytes in the blood of subjects in two groups; D Bar plot of the Th17 cells/lymphocytes in the blood of subjects in two groups; E Bar plot of the Treg/Th17 ratio in the blood of subjects in two groups. (Plot numbers represent the percentage of T-cells in the respective quadrants. Data are shown as means ± SD. ^*P < 0.05, ^**P < 0.01, ^***P < 0.001)
