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 compare the central corneal epithelial thickness (CET), stromal thickness (CST), and total thickness (CCT) in males with and without primary open-angle glaucoma and to determine the factors associated with corneal thickness.

methodsA case-control study was conducted to evaluate 116 male patients at the Miami Veterans Affair Medical Center. Subjects with available anterior segment optical coherence tomography images (Cirrus HD-OCT, Carl Zeiss Meditec Inc, Dublin, CA) were retrospectively classified into 2 groups by glaucoma status. CET, CST, and CCT measurements between the groups were compared. Associations between thickness and other variables of interest were also evaluated.

resultsThe 2 groups were similar with respect to race and ethnicity. Mean age of patients in the glaucoma group (70.3 ± 8.9) was higher than in the nonglaucoma group (66.0 ± 11.7), P < 0.03. Individuals who self-identified as black had lower CST (447.8 ± 29.0 μm) and CCT (503.0 ± 30.5 μm) compared with whites (CST: 470.0 ± 31.7 μm; CCT: 525.1 ± 32.4 μm), P = 0.0001 and P = 0.0002, respectively. In a similar manner, individuals with glaucoma had lower CST (453.4 ± 32.5 μm) and CCT (507.3 ± 33.8 μm) than that of those without glaucoma (CST: 465.2 ± 31.2 μm; CCT: 521.5 ± 31.5 μm), P = 0.05 and P = 0.02, respectively. CET, CST, and CCT were negatively correlated with the number of antiglaucoma medications (r = -0.2, r = -0.22, and r = -0.25, respectively), P = 0.05 for all.

conclusionsIndividuals with glaucoma have lower CST and CCT measurements compared with individuals without glaucoma. An increased number of glaucoma medications were associated with lower thickness measurements.
