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 of glutathione S-transferase (GST) GSTM1, GSTT1, and GSTP1 genes with the risk of primary open angle glaucoma (POAG) and clinical features of the disease.

methodsWe conducted a case-control study that included 87 Brazilian patients with POAG and 85 healthy controls matched for age, ethnicity, and sex, whose blood samples were genotyped for polymorphisms in GST genes using polymerase chain reaction (PCR) based methods.

resultsThe GSTM1 null polymorphism was significantly more common in the POAG than in the controls group (OR: 2.1, 95% CI: 1.13-3.9; p=0.018). The combined GSTM1 null/GSTT1+ genotype and GSTM1 null/GSTP1 Ile/Val or Val/Val was more prevalent in POAG patients, being a risk factor for POAG (OR: 2.4, 95% CI: 1.16-4.9; p=0.016 and OR: 2.7, 95% CI: 1.07-6.74; p=0.033, respectively). The GSTM1 null/GSTT1+ genotype were associated with higher levels of IOP of both eyes and with more severe defect of the right eye optic nerve. The GSTM1 null/GSTP1 Ile/Val or Val/Val genotypes were associated with higher levels of IOP and more advanced defect of the right eye optic nerve and visual field.

conclusionsWe demonstrate that GSTM1 null polymorphism is associated with POAG in the Brazilian population.
