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 measure corneal epithelial thickness (CET) in healthy adults and to investigate its variation with age by use of anterior segment optical coherence tomography (OCT).

methodsA total of 210 healthy individuals were enrolled and divided into four, almost equally sized groups on the basis of age: 18-29 years (group 1), 30-44 years (group 2), 45-59 years (group 3), and 60-80 years (group 4). The CET and total corneal thickness in the central area (diameter 6.0 mm) of each patient were obtained by Fourier-domain OCT, and the regional thickness and topographic variability were compared among the age groups. In addition, the correlations between the CET and age, gender, and refractive status were analyzed using partial correlation tests and multiple regression analysis.

resultsThe CET of the central segment (diameter 2 mm) in groups 1, 2, 3, and 4 were 53.74 ± 3.82, 54.48 ± 3.33, 53.89 ± 3.73, and 53.30 ± 3.36 µm, respectively, demonstrating no significant change with age (P = 0.416). In most of the paracentral and all of the midperipheral zones (annuli 2-5 and 5-6 mm from the center, respectively), the CET differed significantly among the four groups. Correlation analysis suggested that the CET is greater in men than in women and that the CET of both the paracentral and the midperipheral zones is inversely correlated with age. Topographic variability was also inversely correlated with age.

conclusionsThe CET became thinner with age in the paracentral and midperipheral zones, while the central CET seems to remain constant. Gender differences should be considered in the assessment of CET.
