Association of β-fibrinogen polymorphisms and venous thromboembolism risk: A PRISMA-compliant meta-analysis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundVenous thromboembolism (VTE) is a multifactorial disease in which genetic and acquired risk factors may contribute to disease pathogenesis. Several studies have demonstrated that β-fibrinogen (FGB) polymorphisms are associated with the risk of VTE. However, the results of these studies were not totally consistent. In this paper, we performed a meta-analysis to further investigate the relationship between FGB polymorphisms and susceptibility to VTE.
methodsTo identify studies pertinent to the focused question, the following databases were systematically searched: PubMed, EMBASE, Web of Science, China National Knowledge Infrastructure, and Wanfang Data. The strength of correlations was evaluated by calculating pooled odds ratios (ORs) and 95% confidence intervals (95% CIs). Subgroup analyses stratified by ethnicity, type of disorders, and source of control were also performed.
resultsOverall, A total of 18 relevant case-control studies met the inclusion criteria and were incorporated in this meta-analysis, involving 3033 VTE cases and 4547 healthy controls. FGB -455G>A polymorphism and -148C>T polymorphism were not significantly associated with susceptibility to VTE in overall populations. However, results of stratified analysis demonstrated that among Caucasian population, the -455G>A mutation was negatively associated with the risk of VTE under all genetic comparison models (A:G OR = 0.80 95% CI = 0.70-0.91; GA + AA:GG OR = 0.80 95% CI = 0.68-0.93; GA:GG OR = 0.84 95% CI = 0.71-0.98; AA:GG + GA OR = 0.61 95% CI = 0.43-0.87; AA:GG OR = 0.57 95% CI = 0.40-0.82), which indicates FGB -455G>A polymorphism may be a protective factor for VTE. There was no correlation between -148C>T polymorphism and susceptibility to VTE in all subgroup analyses.
conclusionFGB -455G>A polymorphism was associated with a decreased risk of VTE among the Caucasian population.
