Figure 2. Upset plot of CpGs included in our four NEOage clocks. Highlighted in red are the number of CpGs that are unique to each individual clock. Highlighted in orange are the number of overlapping CpGs of clocks that are predictive of either PMA or PNA. Highlighted in blue are the number of CpGs that overlapped in all four clocks (additional information for the 20 common CpGs provided in
