a Comparison of estimated variances of random slopes between the group of individuals with four time points and the group of individuals with two or three time points. b Comparison of chi-square test statistics for the variance of random slope between the group of individuals with four time points and the group of individuals with two or three time points. c The change of standard deviation (SD) in 1507 rsCpG across waves (mean age in each wave in parentheses). Each point represents the SD of DNA methylation for one CpG site in each wave, and the SD of each CpG site in different waves are connected by lines. The overall level of SD across all CpG sites in each wave is shown as a boxplot. The red dashed line is the median SD in wave 1 of LBC1936
