The repeatability of corneal topography measurements in severe Dry Eye disease.
Article in BMC ophthalmology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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.
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
backgroundTo determine the repeatability of corneal topography measurements in severe dry eye disease (DED). A comparison of corneal topography parameters between severe DED and healthy subjects was a secondary goal of this study.
methodsSixty-nine patients with severe DED and 46 healthy subjects were enrolled in the study. All participants underwent repeated corneal topography measurements with Pentacam (Oculus, Germany) within a half hour time. Both eyes of the participants were used in statistical analysis. A further subcategorization of severe DED patients was performed according to Ocular Surface Disease Index (OSDI) scores: 32-50, 51-70 and 71-100. The repeatability of corneal parameters was assessed with correlation coefficients (CC).
resultsThe mean age of dry eye patients and healthy subjects were 40.8 ± 13.2 (17-66) and 39.8 ± 8.2 (18-61) years (p:0.604) respectively. No significant differences were found between severe DED and control groups according to analysed corneal parameters in both eyes (p:>0.05). All CCs were greater than 0.9 in severe DED group (p:<0.001). All CCs were also greater than 0.9 in severe DED patients among different OSDI groups (p:<0.001).
conclusionsCorneal topography measurements are highly repeatable in severe DED with Pentacam. This is the first report about this topic. Nonetheless, further studies are needed with different topography devices for validation.
