Figure 4. The effect of risk factors on the number and function of lymphocytes. (A) Scatter plots showing the number and function of CD4+, CD8+ T cells, and NK cells in high BMI individuals (n=53), low BMI individuals (n=15), and matched healthy controls. (B) Scatter plots showing the number and function of CD4+, CD8+ T cells, and NK cells in individuals with different living habits (smoking, n=50; drinking, n=51; staying up all night, n=59) and matched healthy controls. (C) Scatter plots showing the number and function of CD4+, CD8+ T cells, and NK cells in individuals with different chemistry indexes (hypertension, n=35; hyperglycemia, n=16; hyperlipidemia, n=74; three high, n=13) and matched healthy controls. Three high means hypertension, hyperglycemia, and hyperlipidemia. (D) Scatter plots showing the number and function of CD4+, CD8+ T cells, and NK cells in pregnant women (n=56) and matched healthy controls. Horizontal lines indicate the median. *P < 0.05, **P < 0.01, ***P < 0.001 (Mann–Whitney U-test). BMI, body mass index.
