Angle Kappa is Not Correlated with Patient-Reported Outcomes After Multifocal Lens Implantation.
Article in Clinical ophthalmology (Auckland, N.Z.), 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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 examine the effect of preoperative angle kappa on patient-reported outcomes after multifocal lens placement during cataract surgery and determine if it is an effective measure for preoperative patients screening for multifocal lens placement. Setting: Private refractive surgery clinics. Design: Retrospective cohort study. Methods: All patients undergoing bilateral cataract or refractive lens exchange surgery with a target of emmetropia between 2013 and 2017 at Optical Express (Glasgow, UK) with multifocal lens placement for whom preoperative angle kappa measurement and a postoperative month 1 patient-reported outcomes measures were available were included. Results: A total of 1368 patients were identified. Median preoperative angle kappa was 0.41mm with an interquartile range of 0.30mm to 0.53mm. Preoperative angle kappa did not have a significant association with patient-reported satisfaction with vision (correlation coefficient 0.15, 95% confidence interval -0.081 to 0.39, Conclusion: Angle kappa was not predictive of patient-reported satisfaction in this study. This study did not find evidence that it should be used as a screening test for patients considering multifocal intraocular lens placement.
