Distribution of onset age and the stratified effect of rs2274223 on gastric cancer survival. (a) shows the distribution of gastric cancer onset age in the combined cohorts; the early-onset age was defined as an age <45 years; (b) represents the association between rs2274223 and gastric cancer survival stratified by onset age; the hazard ratios were calculated by the Cox regression analysis with an adjustment for sex, tumor size, histological type and TNM stage in the dominant model.
