  1. aAdjusted for tumor location, 5-fluorouracil treatment status, BRAF V600E somatic mutation status, and tumor stage. Each SNP was analyzed separately adjusting for these factors. Patients with missing data were excluded, resulting in the inclusion of 349 stage I-III patients with MSI-L/MSS tumors
  2. LD calculations indicated that rs11918092 and rs3732568 are in high pairwise LD (r2 = 0.96). In addition, rs1563948, rs11694697, rs11692570, and rs2219613 are all highly linked to each other (0.94 ≤ r2 ≤ 1)
  3. The SNPs listed yielded similar risk estimates under the univariable and multivariable analyses. Consequently, all of the SNPs identified in this study could be considered independent prognostic factors for time-to-metastasis in colorectal cancer if the results are replicated using independent cohort data
  4. Genotype freq. frequency of genotype a calculated from the patient cohort, HR hazard ratio comparing metastasis rate in subgroup a with that in subgroup b, CI confidence interval
