Table 2.

Population I (FAP and AFAP): The table lists combination of genotypes (1 = wildtype genotype, 2 = heterozygote genotype and 3 = variant genotype) and phenotypic FAP group (1 = APC, 2 = APC MCR and 3 = APC AFAP) for each SNP and age where 50% of population I is polyposis free for each genotype. The mutation group/SNP interaction is the p-value from a joint test of the interaction parameters of a Cox model
