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
The correlation between insulin receptor substrate-1 (IRS-1) rs1801278G>A polymorphism and polycystic ovary syndrome (PCOS) has been widely studied. However, the results of these studies are conflicting. The current study provides an assessment of the association between the genetic susceptibilities of IRS-1 rs1801278G>A polymorphism and PCOS. A comprehensive meta-analysis was carried out in over 4,555 subjects included in twenty publications which were published up to June 26, 2015. Our findings suggested that the IRS-1 rs1801278G>A genotype was correlated with the susceptibility of PCOS in the allele comparison, heterozygote comparison and the dominant genetic model. In the dominant genetic model, variant A allele carriers (AA+GA) of IRS-1 rs1801278G>A polymorphism increased the susceptibility of PCOS comparing to the homozygote GG [odds ratio (OR)=1.82, 95% confidence interval (CI) 1.30-2.53 for AA+GA vs. GG]. The analysis by different ethnicity groups highlighted that Caucasian population (OR=1.96, 95% CI 1.26-3.04 for AA+GA vs. GG) had significant increased PCOS susceptibility. Bias diagnosis indicated there are slight publication biases in some genetic models, suggesting that these findings should be interpreted with very caution. In summary, our findings suggested that IRS-1 rs1801278G>A polymorphism may be a risk factor for PCOS.
