Tests of population stratification, batch effects, SNPs disrupting probe hybridization, and systematically inflated p-values all showed the lack of any confounding factors (see Materials and Methods).
The exact interaction of patient population and social factors should be investigated further to identify and fully understand any confounding factors.
Whilst the pedigree accounted for genetic trend, the fitting of a smoothing spline for day of birth protected against any confounding that might have been present.
