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 Apolipoprotein E (APOE), tumor suppressor protein p53 (p53), and cyclin-dependent kinase inhibitor 1A (p21) genes and primary open-angle glaucoma (POAG) in a cohort of Turkish subjects.

methodsSeventy-five POAG patients (49 women, 26 men) and 119 healthy subjects (67 women, 52 men) were genotyped with polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Allele and genotype frequencies between healthy subjects and glaucoma patients were compared by the chi(2) test, and intraocular pressure (IOP), cup/disc ratio (C/D) and visual field indices (MD and PSD) were compared among different APOE, p53, and p21 genotypes in POAG group. A p value <0.05 was considered as statistically significant.

resultsThe mean ages were 63.8+/-9.5 and 61.8+/-10.2 years in POAG and control groups, respectively (p=0.18). There were no significant differences in the distribution of APOE, p53, and p21 genotypes between the healthy subjects and POAG patients (p=0.38, p=0.12, and p=0.2, respectively). There were no significant differences in maximum IOP, MD, and PSD values among different groups of p53 and p21 genotypes (p>0.05). POAG subjects with the epsilon2epsilon3 genotype had a worse PSD value (median=2.2) than those with the epsilon3epsilon4 genotype (median=1.77; p=0.01) and POAG subjects with the epsilon3epsilon3 genotype had worse MD and PSD values (median= -7.4 and 3.4, respectively) than those with the epsilon3epsilon4 genotype (median= -4.1 and 1.77, respectively; p=0.034 and 0.028, respectively).

conclusionsOur study found no link between polymorphisms in APOE, p53, and p21 genes and POAG in Turkish patients, although a larger sample is required to elucidate the role of these polymorphisms in the pathogenesis and course of glaucoma.
