The intrapair analysis is shown for the whole sample as well as for the younger subpopulation. Further the analysis has been run for only MZ and DZ twins respectively.

The simple model is intrinsically adjusted for sex, age, geleffect and zygosity due to the intrapair twin design.

LTL: leukocyte telomere length; MZ: monozygotic twins; DZ: dizygotic twins.
