Fig. 3.

Macaque clocks applied to tissues from vervet monkey (Chlorocebus sabaeus). Each dot corresponds to a tissue sample from vervet monkeys. Each dot is colored by tissue type: blood (green), cerebral cortex (red), liver (purple). Chronological age of the vervet specimens (x-axis) versus the DNAm age estimate of the (A) pan-tissue macaque clock, (B) blood macaque clocks, (C) skin macaque clock, (D) human-macaque clock for chronological age, and (E) human-macaque clock for relative age. Each panel reports the sample size (in parenthesis), correlation coefficient, and median absolute error (MAE)
