«RESULTS: In this current study, a total of 8 eligible studies with 17834 subjects met the inclusion criteria (Figure (Figure1)1) [6–13]. The duration of follow-up ranged from 3 years to 17 years. Three articles reported two cohorts, and each cohort was considered as an independent study. There were 5 case-control studies and 3 cohort studies. There were 4 studies performed using Asians and 4 studies using Caucasians, respectively. Three studies collected the samples from toenails, while other collected from serum. Two studies reported the GC mortality risk. The characteristics of each study included in this meta-analysis are presented in Table Table11.»

Comments: Stratification by smoking status showed that non-smokers with high levels of selenium were associated with decreased GC risk (OR = 0.80, 95% CI 0.70–0.92, P = 0.001). No significant association was found between selenium level and GC risk in smokers (OR = 0.94, 95% CI 0.77–1.14, P = 0.53).
