Table 2.

As described by Eq. (6), this table contains the pairwise overlap between predictors in terms of the variance accounted for by predictor SNPs in common, expressed as a percentage of the total variance accounted for by the SNPs belonging to the predictor for the condition labelling each row. The overlapping variance is weighted according to the sign of the correlation between each pair of associated SNPs (4,000 base pairs or less apart). This can cause diagonal elements to be less than one hundred percent, as anti-correlated SNPs may be included in the overlap calculation.
