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
Purpose: Prior studies in monofocal intraocular lenses (IOLs) suggest that larger Nd:YAG posterior capsulotomies may reduce straylight and photic phenomena, but generalizability to extended depth-of-focus (EDOF) optics is uncertain. We evaluated whether capsulotomy size affects optical quality, higher-order aberrations (HOAs), and patient-reported outcomes in eyes with EDOF IOLs. Patients and Methods: In this prospective single-center study, 106 pseudophakic eyes with visually significant posterior capsule opacification and EDOF IOLs underwent Nd:YAG laser posterior capsulotomy. Capsulotomy size was measured at the slit lamp using a calibrated reticule in the horizontal and vertical meridians; the effective diameter was defined as the mean of these two measurements. Eyes were prospectively assigned to a small opening (S group, n=47), created to slightly exceed the IOL's central diffractive zone (≈1.6-1.8 mm), or a large opening (L group, n=59), extended to the margin of the outermost diffractive ring (≈4 mm). At 1-month post-treatment, visual acuity, HOAs, defocus curves, and optical quality metrics were assessed. Subjective outcomes were evaluated using the APPLES and Catquest-9SF-CN questionnaires. Results: Both groups showed improved visual acuity, with greater corrected distance visual acuity (CDVA) gain in the L group (-0.15 vs -0.06 logMAR; Conclusion: Capsulotomy size significantly influences optical quality and patient satisfaction in eyes with EDOF IOLs. Larger openings improve CDVA and photic symptoms, while smaller ones better reduce spherical aberration but increase trefoil. Personalizing capsulotomy size may optimize outcomes.
