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
purposeCorneal laser refractive surgery is a common procedure for achieving spectacle independence. Impairment of contrast sensitivity following corneal refractive surgery can have far-reaching consequences, such as restrictions for certain professions or driving bans. The objective of this study was to assess contrast sensitivity following corneal refractive surgery and to identify risk factors contributing to lower contrast sensitivity.
methodsThis retrospective study included 174 eyes with a history of corneal laser refractive surgery for myopia correction ≥ 6 months prior who underwent Scheimpflug imaging, a clinical examination, and a test for mesopic binocular contrast sensitivity in glare mode using a Nyctometer. Potential predisposing risk factors were compared between groups with higher and lower binocular contrast sensitivity.
resultsThe uncorrected distance visual acuity was ≥ 0.2 logMAR in 98% of eyes, and the postoperative spherical equivalent was between - 1.5 D and + 1.5 D in 99% of eyes. Moreover, 98% of these patients exhibited a good contrast
conclusionsThe overall refractive and contrast sensitivity outcomes of myopic corneal laser refractive surgery are favourable. In our population, both lower uncorrected distance visual acuity and higher decentration of the effective optical zone are correlated with lower contrast sensitivity.
