A and B, The absolute number and percentage of CD4 and CD8 T cells. The ratios, percentages, and absolute numbers of CD4 and CD8 T cells were determined for each participant using flow cytometry. The cytomegalovirus (CMV)-positive (n = 65) and CMV-negative (n = 22) populations were compared using multivariable linear regression models including age, sex, smoking status, and body mass index as covariables. A Bonferroni correction was applied and P values below .025 were considered significant. Each box represents the mean, the bars represent standard error and the dots represents each individual analyzed.
