Fasting monocyte frequencies and phenotypes in study cohort of healthy adults. A Relation of absolute peripheral blood monocyte counts at fasting and subject age in years. Dark gray line indicates the linear line of best fit. Correlation squared (R²) and the P value for the correlation are shown. B Absolute monocyte numbers at fasting grouped by subject age. C Classical, D intermediate, and (E) non-classical monocytes displayed as percentage of total monocytes grouped by subject age. For B-E, mean and individual data points are shown. Statistical analyses were performed using Kruskal–Wallis non-parametric one-way ANOVA; *P < 0.05, **P < 0.01, ***P < 0.001
