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
aimTo investigate the impact of preoperative anterior corneal topographic parameters on the morphology of the postoperative effective optical zone (EOZ) in patients undergoing keratorefractive lenticule extraction (KLEx) and wavefront-guided LASIK (WG-LASIK).
methodsThis retrospective study included 310 eyes from patients who underwent either KLEx (
resultsA total of 310 eyes were included (KLEx: 171 eyes from 88 patients; WG-LASIK: 139 eyes from 82 patients). The mean age was 30.65±5.67y in the KLEx cohort and 29.06±5.94y in the WG-LASIK cohort. In the KLEx cohort, SE, preoperative mean keratometry (Km), steep keratometry (K2), and anterior corneal astigmatism (K2-K1) were positively correlated with the postoperative optical zone reduction ratio (RR=EOZ/planned optical zone ×100%; all
conclusionPreoperative anterior corneal topographic parameters, particularly anterior corneal astigmatism, significantly affect postoperative EOZ morphology in both KLEx and WG-LASIK. Additionally, Km is a predictor of EOZ reduction specifically in KLEx.
