a Training (upper panel) and testing (lower panel) of the NMR blood clock. b Predicted age (DNAm age) of NMR samples by using ElasticNet regression via 5-fold cross-validation. Linear regression line of the predicted ages is also shown. c Pearson correlation coefficients among the age and the 26 CpG sites of the NMR blood clock. Names of clock sites include accession number of the genomic contig and the genomic position in the contig separated by ‘_’. d Age-related changes in methylation levels of clock CpG sites with the lowest and the highest correlations with age. Number of samples (n), Pearson correlation coefficient (r), its two-sided p-value (p) and the median absolute error (MedAE) are indicated for the specific panels. Source data are provided as a Source Data file.
