1 · What the graph read from it

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.

2 · The registry

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

backgroundFXIII Val34Leu (rs5985) and β-fibrinogen -455G/A (rs1800790) genotypes have been reported to be associated with recurrent spontaneous abortion (RSA). However, this topic is controversial. This study aimed to explore whether FXIII Val34Leu or β-fibrinogen -455G/A gene polymorphisms are related to RSA.

methodsIn this analysis, PubMed, HuGENet and Chinese National Knowledge Infrastructure (CNKI) databases were reviewed. Four models including the dominant model (Val/Val+Val/Leu vs. Leu/Leu), recessive model (Val/Val vs Val/Leu + Leu/Leu), co-dominant model (Val/Val vs. Val/Leu, Val/Val vs. Leu/Leu) and per-allele analysis (Val vs. Leu) were applied. The odds ratio (OR) with 95% confidence interval (CI) was used to assess the association between RSA and FXIII Val34Leu and β-fibrinogen -455G/A polymorphisms.

resultsNine studies with 10 sets of data were included according to the inclusion criterion. A positive association was detected in the pooled results for the dominant model (Val/Val+Val/Leu vs. Leu/Leu; OR = 0.417, 95% CI: 0.180-0.965, I(2) = 45.60%) and co-dominant model (Val/Val vs. Val/Leu; OR = 0.638, 95% CI: 0.452-0.899, I(2) = 36.40%) for FXIII Val34Leu polymorphisms. However, no statistically significant association between β-fibrinogen -455G/A polymorphisms and RSA was detected in the four different models, including the Asian and Caucasian subgroup analyses.

conclusionsOur meta-analysis demonstrates that the FXIII Val34Leu polymorphism has a close association with RSA and women who carry the Val allele for the FXIII Val34Leu polymorphism could have a protective effect against RSA. However, no association is detected between β-fibrinogen -455G/A polymorphisms and the risk of RSA. Future well-designed studies are needed to confirm these results.
