Environmental exposure to polybrominated biphenyl (PBB) associates with an increased rate of biological aging

Figure 1. Correlation of chronological age and biological age. Chronological age was positively correlated with each of the three epigenetically-predicted ages. Intrinsic age and chronological age were highly correlated (r = 0.91, p < 2.2e-16, (A), as were extrinsic age and chronological age (r = 0.91, p < 2.2e-16, (B), and phenotypic age and chronological age (r = 0.91, p < 2.2e-16, (C). The red line indicates the regression of the epigenetically-predicted age on the chronological age. The blue line is a 1:1 line for comparison.
