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
purposeTo assess the retinal peripheral defocus changes following femtosecond laser in situ-keratomileusis (FS-LASIK) in myopic adults and analyse influencing factors.
methodsThis study recruited 202 patients who underwent FS-LASIK with myopia at Beijing Ming Vision Eye Hospital. Participants were divided into low myopia (LM, -0.50D to -3.00D), moderate myopia (MM, -3.00D to -6.00D), and high myopia (HM, ≥-6.00D) groups according to spherical equivalent (SE). We measured axial length (AL), total retinal defocus (TRDV), and defocus values at eccentricities ranging from 0° to 53° from the fovea, and defocus values at the superior, inferior, temporal, and nasal quadrants. With a 3-month follow-up, changes in peripheral defocus (ΔRDV) were recorded and analysed.
resultsNo significant differences were observed in TRDV, RDV20°-53°, and RDV-S among the three groups after surgery (all P > 0.05). RDV at 10°-53° increased with eccentricity, while all groups showed significant reductions in hyperopic defocus at 20°-53° compared to preoperative measurements (all P < 0.05). This reduction was more pronounced with severe myopia and greater eccentricity. Correlation analysis revealed that ΔRDV20°-30° and ΔRDV30°-40° positively correlated with SE and negatively correlated with AL and cutting thickness. ΔRDV40°-53° negatively correlated with AL. ΔRDV-T negatively correlated with SE, ΔRDV-N positively correlated with SE and negatively correlated with AL and cutting thickness (all P < 0.05).
conclusionFS-LASIK does not change the asymmetric distribution of RDV after surgery. It effectively reduces hyperopic defocus within the 20°-53° range around the fovea, with greater reductions noted peripherally. Higher myopia and greater cutting thickness are associated with larger defocus reductions.
