Association of increasing order of MMP-1 polymorphic variant alleles in haplotypes with Lower stomach gastric cancer risk.

Haplotypes order as MMP-1.1-MMP-1.2-MMP-1.3-MMP-1.4-MMP-1.5.(a) two sided χ2 Association P value, OR = Odds ratio, CI = Confidence Interval, Ref = Reference haplotype to calculate OR. Other possible combinations of linked loci are omitted because of null frequency in the population. Haplotype frequency and haplotype association test performed using Haploview4.2 software. Haplotype numbers denote the number of risk allele(s) present in the haplotypes.
