**Figure 11.** **Predictabilities: Differences between demographics. **(**A**) Correlation between the predictabilities of the 50 biomarkers in the first group and the predictabilities of the 50 biomarkers in the second group. The diagonal black line represents a perfect correlation. The further away from this line the points lie, the bigger the difference between the two groups, and the lower the correlation. (**B**) Volcano plots reporting the significance and the size of the baseline (calculated on the full age range 20-80) differences between the groups. The horizontal black lines represent the threshold of significance of 0.05 for the Bonferroni corrected p-values. (**C**) Volcano plots showing which predictabilities are changing at significantly different rates with age in different demographic groups. The horizontal black lines represent the threshold of significance of 0.05 for the Bonferroni corrected p-values.
