Figure 1: Within-individual age variations (delta age) of (A) leukocyte concentration and profiles for (B) the relative number of lymphocytes, (C) neutrophils, (D) monocytes and (E) eosinophils. Dots represent the raw data with size proportional to the sample size. Black solid lines represent model predictions with their 95% prediction interval (grey areas). Model predictions and their intervals were obtained over all samples for (A) and by fixing the continuous variables to their mean over all samples and the sex to female, the year to 2013 and the individual random effect to a given individual for (B, C, D, E).
