1 · What the graph read from it

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.

2 · The registry

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

Background: AM2UH was a novel bifocal hybrid extend the depth of focus (EDF) intraocular lens (IOL). This study is to evaluate the effectiveness and safety by comparing it with a monofocal IOL (AW-UV). Methods: A prospective, comparative, single-center study. 37 patients (37 eyes) were implanted with novel hybrid EDF IOL model AM2UH. 36 patients (36 eyes) were implanted with monofocal IOL model AW-UV. At 6 months postoperatively, the visual acuity (uncorrected and distance corrected), defocus curves, refractive outcomes, contrast sensitivity, questionnaires of visual quality were assessed and compared between 2 groups. Results: Compared to AW-UV, AM2UH showed non-inferior monocular corrected distance visual acuity ( Conclusion: AM2UH IOL is an effective and safe EDF IOL that offers satisfactory intermediate vision and distance vision, improves near vision, and delivers an extended visual range while maintaining favorable visual quality. Clinical trial registration: Identifier: MR-50-25-086616.
