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

purposeTo investigate the association between VEGF gene polymorphism and age-related macular degeneration (AMD) in a Brazilian cohort.

methodsWe examined 160 affected individuals and 140 sex- and age-matched controls recruited at the Vision Institute and the Retina Department, São Geraldo Hospital, Minas Gerais Federal University, Brazil, between 2007 and 2011. Genotyping for the VEGF rs1413711 single nucleotide polymorphism (SNP) (+674C>T) was performed. The incidence rate ratios and 95% confidence interval (CI) for AMD for this genotype was calculated. The odds ratio (OR) was also assessed by using logistic regression, controlling for CFH and LOC387715 risk genotype.

resultsWe observed a prevalence of homozygosity (TT genotype) of 18.1% for rs1413711 among AMD cases compared with 5.8% among controls (P < 0.002). The ORs for this polymorphism were 3.6 (95%CI 1.6-8.2) for homozygous subjects and 1.5 (95%CI 1.1-2.1, P < 0.01) if the subject had at least one risk allele. When we studied separately exudative and dry AMD groups, this polymorphism was statistically significant for both groups. Controlling for CFH and LOC387715 risk genotype the OR was 3.0 for VEGF homozygous, and the OR increases if the patient is homozygous for the three genes.

conclusionThe present data suggests that VEGF TT genotype is associated with AMD among Brazilian patients.
