Risk factors for biometry prediction error by Barrett Universal II intraocular lens formula in Chinese patients.

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
aimTo investigate the influence of postoperative intraocular lens (IOL) positions on the accuracy of cataract surgery and examine the predictive factors of postoperative biometry prediction errors using the Barrett Universal II (BUII) IOL formula for calculation.
methodsThe prospective study included patients who had undergone cataract surgery performed by a single surgeon from June 2020 to April 2022. The collected data included the best-corrected visual acuity (BCVA), corneal curvature, preoperative and postoperative central anterior chamber depths (ACD), axial length (AXL), IOL power, and refractive error. BUII formula was used to calculate the IOL power. The mean absolute error (MAE) was calculated, and all the participants were divided into two groups accordingly. Independent
resultsA total of 261 patients were enrolled. The 243 (93.1%) and 18 (6.9%) had postoperative MAE<1 and >1 D, respectively. The number of females was higher in patients with MAE>1 D (
conclusionRisk factors for biometry prediction error after cataract surgery include the patient's sex and postoperative ACD. Patients with a shallow postoperative anterior chamber are prone to have refractive errors.
