Association between chronotype and cardio-vascular disease risk factors: A systematic review and meta-analysis

The Association between GNB3 Gene Polymorphism and Obesity: A Systematic Review and Meta-Analysis

The association between Guanine Nucleotide Binding protein β protein polypeptide 3(GNB3) C825T polymorphism and obesity has recently been reported. However, the findings remain inconclusive. The aim of this systematic review and meta-analysis was to detect the relationship between GNB3 C825T polymorphism and obesity. Materials and Methods: Six electronic databases including Embase, Medlin...

The association between anemia and postpartum depression: A systematic review and meta-analysis

Association between Environmental Dioxin-Related Toxicants Exposure and Adverse Pregnancy Outcome: Systematic Review and Meta-Analysis.

Dioxin-related compounds are associated with teratogenic and mutagenic risks in laboratory animals, and result in adverse pregnancy outcomes. However, there were inconsistent results in epidemiology studies. In view of this difference, we conducted a systematic review and meta-analysis to examine this association and to assess the heterogeneity among studies. Comprehensive literature searches w...

A systematic review and meta-analysis on the association of serum and tumor tissue iron and risk of breast cancer

Background: Some studies have investigated the effects of iron on breast carcinogenesis and reported different findings about the association between Fe and breast cancer risk. This study was conducted to estimate this effect using meta-analysis method. Methods: A total of 20 articles published between 1984 and 2017 worldwide were selected through searching PubMed, Scopus, Embase, Web of Scien...

Association between Tumor Necrosis Factor- α-308 G/A Polymorphism and Multiple Sclerosis: A Systematic Review and Meta-Analysis

Multiple sclerosis (MS) is a complex polygenic disease in which gene-environment interactions are important. A number of studies have investigated the association between tumor necrosis factor-α (TNF-α) -308 G/A polymorphism (substitution G→A, designated as TNF1 and TNF2) and MS susceptibility in different populations, but the results of individual studies have been inconsistent. Therefore, per...
