  1. aFor |D'| TA n repeat lengths were divided into eight categories, ≤10, 11, 12 or 13, 14–16, 17, 18, 19, or >20. This ensured that there were few cells that contained fewer than five observations. For r 2 the TA n repeat is dichotomised. bAll |D'| values are statistically significant at α = 0.001.
