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
objectiveThis study aimed to analyse the correlation between corneal astigmatism and disparity in corneal thickness.
methodsIn this retrospective analysis, data from 342 patients (684 eyes) were collected. The Sirius three-dimensional corneal topography system was utilised to ascertain the mean corneal thickness of the meridians. Correlation analyses were conducted between the mean difference in corneal thickness along the two principal meridians and the astigmatic values computed by simulated keratometry values (Sim-K) for total corneal astigmatism (TCA) and posterior corneal astigmatism (PCA), respectively. Variability in differential corneal thickness (DCT) values at different TCA levels was analysed. The variability of DCT within the 3-mm corneal range at different differences between whole-eye astigmatism and TCA (Difference between corneal astigmatism and computer optometry, DWT) levels was analysed.
resultsWithin the ranges of 3, 4.5, and 6 mm, the mean corneal thickness of the meridian with the maximum refractive power (Sim-K
conclusionThe meridian with the maximum refractive power had a thicker mean corneal thickness than the meridian with the minimum refractive power. The difference in corneal thickness is closely related to the severity of corneal astigmatism. The extent of residual astigmatism is influenced by this thickness difference.
