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: To develop a correlation of simulated modulation transfer function (MTF) to clinical monocular and binocular visual acuity (VA) to predict the VA defocus curves of intraocular lenses (IOLs) in the early preclinical development. Methods: Ray tracing software was used to generate MTF area (MTFa) data at defocus positions from -3.0 D to +2.0 D. which were then correlated with clinical monocular and binocular VA data to predict preclinical metrics. Simulated MTF data was generated (with mean photopic pupil size of 3 mm with photopic spectral weighting) in a modified pseudophakic Navarro eye model, with corneal spherical aberration (SA) both at the matched and the average human corneal SA. MTFa was calculated across two spatial frequency ranges, and linear and polynomial functions were fit to the pairs of MTFa Results: Simulated MTFa (with mean photopic pupil size of 3 mm with photopic spectral weighting) is broadly well correlated with clinical VA ( Conclusion: Monocular and binocular fittings showed similar correlation coefficients for the prediction of VA. VA calculated from simulated MTFa can be an accurate predictor of the clinical performance of an IOL design, helping to identify promising IOL designs early in the development process, improving optical quality and reducing the risk of suboptimal lenses advancing to manufacturing and clinical trials.
