Roles of three common VEGF polymorphisms in the risk of age-related macular degeneration.

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
Associations between vascular endothelial growth factor (VEGF) polymorphisms (rs833061, rs1413711, and rs3025039) and risk of age-related macular degeneration (AMD) have been extensively studied, but the currently available results are contentious rather than conclusive. Therefore, we performed the present meta-analysis to further assess the associations. Literature search in PubMed, Embase, and Web of Science databases was conducted until April 2013. The strength of the associations between VEGF polymorphisms and AMD risk was estimated by pooled odds ratios (ORs) and 95% confidence intervals (CIs). Both models of fixed effects and random effects were performed to summarize the pooled ORs. All data were analyzed by Stata software 12.0. The meta-analysis results based on nine case-control studies with 2427 cases and 2037 controls showed that rs833061 had protective effects on AMD risk (TT vs. CT+CC: OR=0.58, 95% CI=0.41-0.81), whereas rs1413711 (TT vs. CT+CC: OR=1.46, 95% CI=1.10-1.93) and rs3025039 (TT vs. CC: OR=1.87, 95% CI=1.15-3.02; TT vs. CT+CC: OR=2.09, 95% CI=1.30-3.37) represented as risk factors for AMD. Subgroup analysis by ethnicity suggested significantly reduced risk in Caucasians (TT vs. CT+CC: OR=0.60, 95% CI=0.36-0.99; T vs. C: OR=0.89, 95% CI=0.78-1.00) and Asians (TT+CT vs. CC: OR=0.57, 95% CI=0.34-0.96; TT vs. CT+CC: OR=0.54, 95% CI=0.33-0.90) for rs833061, yet elevated risk in Caucasians (TT vs. CT+CC: OR=2.05, 95% CI=1.24-3.38) for rs1413711 and in Asians (TT vs. CC: OR=2.06, 95% CI=1.24-3.43; TT vs. CC: OR=2.34, 95% CI=1.42-3.89) for rs3025039. In stratified analysis by type of AMD, rs833061 was observed to decrease wet AMD risk, while rs1413711 and rs3025039 were found to increase the risk of wet AMD. Based on the currently available data, this meta-analysis suggests that the VEGF polymorphisms may be associated with risk of AMD, particularly wet AMD.
