Figure 1. Telomere length characteristics at baseline.
A) Mean relative telomere length (RTL) at baseline in control (n = 30), PD (n = 124), PSP (n = 17) and MSA (n = 13) samples. Age-adjusted p-values comparing control with patient subgroups. B) RTL as a function of age at baseline with regression lines. Correlation between telomere length and age in control and patient subgroups examined using the Pearson's correlation coefficient. No significant (p = 0.394) difference in the relationship between RTL and age was found in control and patient groups.
