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, refractive, and optical performance of two diffractive trifocal intraocular lenses (IOLs) with analogous designs but different light distribution profiles.
methodsA total of 54 eyes from 48 patients undergoing cataract surgery received either the Gemetric™ (GM; Hoya Surgical Optics, Singapore) or the Gemetric™ Plus (GMP; Hoya Surgical Optics) IOLs. Preoperative demographics were comparable between the two groups. Generalized estimating equations (GEE) were utilized for statistical analysis to adjust for inter-eye correlations.
resultsA total of 48 patients (54 eyes) were included in the analysis, of which 30 patients (33 eyes) received the GM IOL and 18 patients (21 eyes) the GMP IOL. The mean age was 59.6±6.1y (range: 48-72) in the GM group and 61.6±5.8y (range: 49-69) in the GMP group (
conclusionAdjusting light distribution in otherwise identical trifocal IOLs results in distinct clinical and optical advantages, allowing surgeons to tailor IOL selection to patients' specific visual demands.
