Figure 1. 353 CpG “epigenetic clock” age prediction in white blood cells and cumulus cells. Black line indicates a perfect prediction of chronological age (y=x). Study groups are indicated with colors: Red A= <35 years old and good responder (≥15 mature follicles), green B= <35 years old and poor responder (≤5 mature follicles), blue C= >40 years old and poor responder (≤4 mature follicles) and magenta D= >40 years old and good responder (≥12 mature follicles). Tissue types are indicated by symbols.
