  1. Pooled analyses for studies with p53 information (ABCS and HEBCS); HRs of heterozygous and homozygous rare allele groups have been calculated by comparison to the reference categories of the homozygous common allele: TP53 R72P = GG, and MDM2 SNP309 = TT; analyses have been adjusted for study, age, stage, grade and ER.
