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 compare the visual performances of extended depth of focus (EDOF) lenses, diffractive bifocal intraocular lenses (IOLs) and their combination.
methodsThis was a prospective, consecutive observational comparative study performed from Dec 2020 to Dec 2021. Cataract patients who meet the indications for multifocal IOLs implantation were divided into three groups, including binocular diffractive bifocal IOL (Human Optics Diff-aAY) implantation group, binocular EDOF IOL (Tecnis Symfony ZXR00) group and mix-and-match group (Symfony in one eye and Diff-aAY in the other). Follow-ups were scheduled at 1d, 3d, 2wk, and 6mo. Visual acuities (VA) at different distances were examined at every follow-up. At 6mo, optic path difference (OPD) scans, and questionnaire answers were evaluated.
resultsThirty patients (60 eyes) were included in the binocular Diff-aAY group [age 63 (59-68), 11 males], 29 patients (58 eyes) in the binocular Symfony group [age 62 (56.75-68), 15 males] and 27 patients in mix-and-match group [age 65 (51-71), 11 males]. There was no significant difference in binocular uncorrected distance VA, uncorrected intermediate VA, or uncorrected near VA among the three groups (
conclusionBilateral Symfony, bilateral Diff-aAY, and the combination of these two IOLs are all remarkable regarding all range vision, objective visual quality, and spectacle independence.
