GSTP1 and gastritis: The analyses showed that individuals carrying the homozygous GSTP1*G/G rs1695 variant genotype exhibited three times higher odds (OR = 3.21, 95%CI = 1.15–8.91, p = 0.025), while carriers of at least one GSTP1*T rs1138272 variant allele had two times higher odds of developing HP-positive gastritis (OR = 2.31, 95%CI = 1.14–4.89, p = 0.021) compared with those carrying reference alleles.
