Figure 3. Age stratified analyses comparing association between lung and age accelerations. (A) Comparison between association between FEV1 and age accelerations (AAres and IEAA); (B) Comparison between association between FVC and age accelerations (AAres and IEAA). X-axis represents stratifications by 10 years intervals. Y-axis represents the estimates (changed in lung function per year of epigenetic age acceleration in mL/year) from the linear models with 95% confidence intervals.
