seAFOod trial participant samples
COLORECTAL POLYP
A total of 666 trial participants had at least one buffy coat sample vial in the seAFOod trial biobank (seAFOod trial participants and samples contributing to the gene × treatment interaction analysis. 666 of 707 seAFOod trial participants provided at least one buffy coat sample for DNA extraction. The number of samples lost during either DNA extraction or SNP genotyping is described at each stage. The final study population consisted of 542 participants for whom SNP genotype and trial exit colonoscopy data were available. EPA, eicosapentaenoic acid; SNP, single-nucleotide polymorphism.A total of 542 seAFOod trial participants, for whom SNP genotype data were available, also had colonoscopy outcome data from the seAFOod trial. Reasons for lack of primary (colorectal polyp) outcome data for some trial participants are detailed in the seAFOod trial CONSORT diagram (Clinical characteristics of the study cohort of 542 seAFOod trial participants who had a SNP genotype profile and trial colonoscopy outcome data.
