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

backgroundKeratoconus (KC) is a degenerative eye disease which results from thinning of the cornea and causes vision distortion. Oxidative stress damage to KC corneas may be because of the failure of corneas to process reactive oxygen species which leads to corneal thinning and loss of vision. Genetic variants in antioxidant defense genes such as catalase (CAT) and glutathione peroxidase (GPX) can decrease antioxidant capacity or increase oxidative stress and alter the risk of KC in patients. We investigated and evaluated the effects of single nucleotide polymorphisms in CAT, GPX-1 on the risk of KC in an Iranian population sample.

methodsThis case-control study was performed on 140 patients with KC and 150 healthy control subjects in a sample of Iranian population from Zahedan, southern Iran in 2015. Genotyping of CAT rs7943316 and GPX-1 rs1050450 polymorphisms was done using polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) method.

resultsCAT rs7943316 A/T, AA genotype and A allele have a protective role against disease (OR =0.28, 95% CI =0.13-0.61,

conclusionCAT rs7943316 A/T, AA genotype, and A allele decreased the risk of KC. Moreover, in GPX-1 rs1050450 C/T polymorphism, T allele was associated with an increased risk of KC in our population.
