Binary logistic regression analysis was carried out with the purpose of establishing a model against the estimation of the risk of mortality from gastric cancer and the presence of the variables of interest such as high level of IL-4 and presence of − 1082 (G/A) SNP in promoter sequence of the IL-10, among others, with its respective coding, using “dummy” variables (Table 5). This evidence concerns the gene IL4 and gastric cancer.
