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

purposeGlaucomatous eyes with disc hemorrhage (DH) have a greater risk of paracentral visual field (VF) loss. However, not every DH eye presents with parafoveal scotoma (PFS), and contributing factors are still to be determined. In the present study, we investigated clinical and ocular factors associated with the presence of PFS in glaucomatous eyes with DH.

methodsA case-control study was carried out. One hundred thirty glaucomatous patients with DH were enrolled. They were divided into two groups based on two reliable 24-2 VF tests: those with PFS (defined as ≥3 adjacent points with p < 5% within the central 10 degrees of fixation, ≥1 point with p < 1% lying at the innermost paracentral points, in the same hemifield) and those without PFS. Clinical and ocular data from the time of DH detection were compared between groups. Factors associated with the presence of PFS were investigated through logistic regression.

resultsThe PFS group had a higher prevalence of Caucasian patients (82 vs. 47%; p < 0.01). Eyes with PFS had a more negative spherical equivalent and worse VF mean deviation (MD) index (p ≤ 0.01). There was a marginally significant intraocular pressure (IOP) difference between eyes with (15 mmHg) and without PFS (18 mmHg) at the time of DH detection (p = 0.10). Univariable analysis revealed PFS to be significantly associated with Caucasian race (OR, 3.02; p = 0.004), myopia (<-3 diopters; OR, 3.44; p = 0.039), and lower IOP (≤16 mmHg; OR, 2.10; p ≤ 0.047). Multivariable analysis, controlling for VF MD, revealed that only Caucasian race and myopia (as a continuous or categorical variable) remained significant in this model (p ≤ 0.038).

conclusionsCaucasian race and the presence and magnitude of myopia were found to be significantly associated with the presence of PFS in glaucomatous eyes with DH. Our results may help clinicians in the identification and surveillance of these eyes at higher risk of central VF loss.
