COL1A1 gene -1997G/T polymorphism and risk of osteoporosis in postmenopausal women: a meta-analysis
Studies investigating the association between the COL1A1 gene -1997G/T polymorphism and the risk of osteoporosis in postmenopausal women have reported conflicting results. We performed a meta-analysis based on the evidence currently available from the literature to make a more precise estimation of this relationship. We conducted searches of the published literature in the PubMed and Embase databases up to September 2014. We estimated the pooled odds ratios with their 95% confidence intervals to assess the associations using fixed- or random-effect models.
