Fig. 3

A–C Scatterplots of GPx3 intensity (proteomics data) and biological age estimators. The x-axis is log-scaled. D–F Boxplots of biological age estimators stratified by quartiles of GPx3 intensity (proteomics data, Q1: 11.6–12.7, Q2: 12.71–12.90, Q3: 12.91–13.10, Q3: 13.11–13.6). Statistical significance of difference between group means was assessed by t-test. Note: DNAmAA = DNA methylation age acceleration; biolog. = biological years; chron. = chronological years. Boxplots show the median, hinges (corresponding to 25 th and 75 th percentile) and whiskers (1.5*inter-quartile range (IQR))
