Previous reports have suggested a potential association on dietary zinc intake with the risk of pancreatic cancer. Since the associations between different studies were controversial, we therefore conducted a meta-analysis to reassess the relationship between dietary zinc intake and pancreatic ca...

OBJECTIVE: Epidemiological studies have repeatedly investigated the association between excess body weight and the risk of biliary tract cancer with inconsistent results. The objective of this study was to quantitatively assess the associations between overweight and obesity and the risk of bilia...

BACKGROUND: Several observational studies suggest that coffee consumption may be associated with an increased risk of gastric cancer, but the results are inconsistent. We conducted a meta-analysis to evaluate the relationship of coffee consumption with gastric cancer risk and quantify the dose-re...

BACKGROUND: Upper respiratory tract infections (URTIs) are common and burdensome infectious illness. Several trials have reported that probiotics can prevent URTIs in adults. OBJECTIVES: To evaluate the efficacy and safety of probiotics in the prevention of URTIs in adults. METHODS: PubMed, Web o...

Inulin-type fructan (ITF) intake has been suggested to alleviate several features of metabolic syndrome including obesity, diabetes, and hyperlipidemia; yet, results from the human trials remained inconsistent. We aimed to systematically evaluate the effects of ITF intake on body weight, glucose ...

OBJECTIVE: Overweight was regarded as one of the risk factors for poor outcome after gastrectomy, but its influence on the surgical and postoperative outcomes of gastrectomy was unclear. METHODS: Comprehensive searches were conducted to include cohort studies which evaluated the influence of over...

BACKGROUND AND AIMS: A number of studies have shown that polymorphisms in the vitamin D receptor (VDR) gene are implicated in susceptibility to type 2 diabetes (T2D). However, the results are inconsistent and inconclusive. METHODS: A meta-analysis was performed to analyze the association among th...

BACKGROUND: Previous studies regarding the association between cruciferous vegetable intake and pancreatic cancer risk have reported inconsistent results. We conducted a meta-analysis to demonstrate the potential association between them. METHODS: A systematic literature search of papers was cond...

OBJECTIVE: To clarify and quantify the potential dose-response association between the intake of fruit and vegetables and risk of type 2 diabetes. DESIGN: Meta-analysis and systematic review of prospective cohort studies. DATA SOURCE: Studies published before February 2014 identified through elec...
