ICC (95% CI) of cytokine levels stratified by the median (4.49 years) of time interval between the 1st and 3rd measures. The dots and horizontal bars represent the ICC and corresponding confidence intervals, respectively. Results of the subjects with time spans < 4.49 years (n = 32) and ≥ 4.49 years (n = 33) were plotted in the panel (a) and (b), respectively. ICC: intraclass correlation coefficient; CI: confidence interval
