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
objectiveTo evaluate detailed regional changes in corneal epithelial thickness after orthokeratology treatment according to the targeted refractive power.
methodsThis retrospective study included a total of 63 eyes of 44 patients who underwent overnight orthokeratology for the correction of myopia. Corneal epithelial thickness was segmentally measured using anterior segment optical coherence tomography before and after treatment.
resultsIn the central zone (0-2 mm), the corneal epithelial thickness was significantly decreased by 7.54±5.46 μm ( P <0.05). In the paracentral zone (2-4 mm), it was also significantly decreased in all sectors, with the greatest thinning found in the temporal area. In the midperipheral zone (4-6 mm), it was significantly increased especially in the superior superonasal area, whereas in the peripheral zone (6-7 mm), it was also significantly increased especially in the inferior temporal area. The changes in the epithelial thickness within the central 4-mm area was significantly correlated with the amount of the target refractive power in both low- and high-correction groups. The geography pattern of corneal epithelial redistribution was in accordance with the overall trend of the orthokeratology lens fitting decentration.
conclusionsOrthokeratology induces central epithelial thinning and peripheral thickening with an asymmetric redistribution, presumably due to inferior temporal lens decentration. Eyes with higher refractive correction showed greater changes in the corneal epithelial thickness.
