Figure 2

Numbers of risk alleles in DNA repair genes among the adolescents and the 'elderly'. The dashed line represents the cut-off point between the relatively low (≤8) and high (> 8) sum of risk alleles (see methods). The number of persons with nine to fourteen at-risk alleles is smaller among the elderly (p = 0.017). As can be seen from the figure, among the "elderly" the group with 8 at risk alleles counts the most subjects, more then hundred (109), whereas among the adolescents the group with 9 at risk alleles counts the most subjects, more the hundred (104).
