  1. Note: PRS were calculated for variants from the final stepwise model with allele dosage from OncoArray and iCOGS weighted by the per-allele conditionally adjusted odds ratios from the meta-analysis
  2. aRisk category groups were based on the percentile distribution of risk alleles in overall controls
  3. bEstimated effect of each PRS group relative to the interquartile range (25–75%) in OncoArray and iCOGS datasets separately, and then meta-analyzed across the two studies; odds ratios were adjusted for country and 7(OncoArray)/8(iCOGS) principal components
