Summary of the validation and stability of the age-positions. Plots show temporal changes in age-positions in the validation dataset for VL muscles (A) and in brain cortex (B). The age-position is denoted with the number of associated probes. Original datasets are denoted with a black line. The number of samples and the age range of every dataset is indicated under the X-axis. Age-positions in VL muscles. The age range (depicted with a line) and the number of samples per dataset is denoted under the X-axis. Absolute correlation k-means clustering plots for each dataset are shown in the Additional file 1.
