Figure 4

Anticipated results of absolute telomere length in lymphocytes and buccal cells. This cohort comprised 18 males (grey bars) and 25 females (open bars) in the young group (aged 18-31 years), and 25 males (grey bars) and 23 females (open bars) in the older group (65-75 yrs). Graph A shows the lymphocyte telomere length decreases with age in both males and females; Graph B shows buccal cell telomere length decreases with age in males, not in females. Data are shown as box plots which represent five-number summary of the data (the minimum, lower quartile, median, upper quartile and maximum).
