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 evaluate the incidence, risk factors, and surgical management of CTR-IOL-CB complex subluxation/dislocation in a low-pseudoexfoliation area. Methods: Patients with CTR-IOL-CB complex subluxation/dislocation who had complete medical records at the Qingdao Eye Hospital of Shandong First Medical University between January 1994 and April 2024 were selected. Patient demographic data, incidence, interval, risk factors, extent of zonular weakness, IOL and CTR design and material, surgical management, visual acuity (VA), and other complications. Results: 31 cases aged 65.17 ± 7.19 years at CTR-IOL-CB complex subluxation/dislocation were reviewed; the interval was 41.23 ± 14.63 months after implantation of IOL and CTR. The incidence rate of CTR-IOL-CB complex subluxation/dislocation was 0.85%. The most common risk factors were ocular trauma and hypermature cataract. Extent of zonular weakness of ≥4 o'clock and the use of 1-piece hydrophilic acrylic and 3-piece hydrophobic acrylic IOLs were susceptible to complex subluxation/dislocation. VA was significantly increased after IOL repositioning or exchange; no other complications were present. Conclusion: Zonular insufficiency stabilized with IOL and CTR alone still carries a risk of re-dislocation. Ocular trauma and hypermature cataract were the most common risks in a low-pseudoexfoliation region. IOL exchange or repositioning is effective for this complication.
