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 investigate differences in objective and subjective visual quality 12 months following Q value-guided (Custom-Q) femtosecond laser-assisted laser in situ keratomileusis (FS-LASIK) versus small incision lenticule extraction (SMILE) for correction of low-to-moderate myopia and compensate for age-related accommodation deficiency.
methodsClinical data of 45 patients were analyzed, of whom 23 were treated with FS-LASIK and 22 with SMILE. At the 12-month follow-up, the distance, intermediate, and near visual acuities; objective and subjective refractions; Q factor; corneal higher-order aberrations (HOAs); defocus curve; contrast sensitivity; stereopsis and a subjective visual quality questionnaire were evaluated.
resultsAt 12 months postoperatively, the two groups had comparable binocular uncorrected distance and intermediate visual acuities (UDVA, UINA). A slightly better uncorrected near visual acuity (UNVA) was observed in the FS-LASIK group (P < 0.05), but patients reported equivalent near vision satisfaction and spectacle independence. Total HOAs and coma increased significantly in all treated eyes (P < 0.05). The Q value and spherical aberration (SA) became more positive, but the shifts were significant only in the SMILE group and the dominant eyes of the FS-LASIK group (P < 0.05). Binocular contrast sensitivity was better in the FS-LASIK group. No significant differences in visual disturbances were found between groups.
conclusionFor myopic patients with mild age-related accommodation deficiency, both FS-LASIK with Custom-Q protocol and SMILE could provide good efficacy, safety, predictability, and high patient satisfaction. The Custom-Q protocol could better preserve the original prolate shape of the cornea and achieve superior visual quality compared to SMILE. KEY MESSAGES: What is known Both femtosecond laser-assisted laser in situ keratomileusis (FS-LASIK) and small-incision lenticule extraction (SMILE) have been widely applied in young myopic patients, with comparable efficacy and safety. Studies evaluating the clinical outcomes of FS-LASIK and SMILE in treating myopia with age-related accommodation insufficiency are lacking. What is new For myopic patients with mild age-related accommodation deficiency, both FS-LASIK with Custom-Q protocol and SMILE could provide good efficacy, safety, predictability, and high patient satisfaction. The Custom-Q protocol could better preserve the original prolate shape of the cornea and achieve superior visual quality compared to SMILE.
