Table 2A details the ORs of CRC and adenoma and corresponding 95% CIs associated with TGFBR1*6A hetero- and homozygosity in the two familial CRC groups. When performing test for association restricting affection status in cases to CRC (non-HNPCC, n=132; HNPCC, n=82), corresponding ORs were similar (Table 2B). This evidence concerns the gene TGFBR1 and adenoma.
