Risk factors for error in refractive astigmatism after toric intraocular lens implantation in Chinese patients.
Article in BMC ophthalmology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundTo evaluate the risk factors for postoperative error in refractive astigmatism (ERA) in Chinese patients with cataract and astigmatism undergoing toric intraocular lens (IOL) implantation.
methodsRetrospective study. 132 patients who underwent cataract surgery with toric IOL implantation performed by a single surgeon at Peking University Third Hospital Department of Ophthalmology were enrolled. The Barrett Toric Calculator was used to calculate IOL power. Data collected included the patient's best-corrected visual acuity (BCVA), corneal curvature, central anterior chamber depth (ACD), axial length (AL), incision position, and IOL sphere and cylinder diopters. Corrected visual acuity, ERA, corneal curvature and ACD were collected 1 month after operation. All the participants were divided into two groups according to ERA(whether within 0.5 D or not).Logistic regression was performed to analyze the risk factors for postoperative ERA.
results112 of the 132 patients (84.8%) had a < 0.5 D postoperative ERA. Logistic regression model showed that older age (OR = 1.102, 95% CI: 1.019-1.192), longer AL (OR = 1.611 95% CI: 1.069-2.429), and higher ΔACD (OR = 4.035, 95% CI: 1.086-15.00) were independent risk factors for postoperative ERA. However, gender, preoperative astigmatism, incision position were not independent risk factors for ERA.
conclusionsFactors contributing to ERA after toric IOL implantation include age, AL and ACD change before and after the surgery.
