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
objectivesThe weakness and dialysis of lens zonule after cataract surgery may lead to dislocation of intraocular lens (IOL). It has been shown that cataract surgery could induce or aggravate posterior vitreous detachment (PVD) due to postoperative inflammation and increased volume of vitreous cavity. PVD is associated with the occurrence of several vitreoretinal diseases, such as rhegmatogenous retinal detachment and macular hole. This study aims to explore risk factors for dislocation of IOL concurring with vitreoretinal disease, such as retinal detachment and macular hole, and to evaluate the efficacy and complications of surgical intervention for these abnormalities concurrently.
methodsTen patients (10 eyes) who diagnosed as rhegmatogenous retinal detachment, traumatic macular hole, high myopic macular hole, and combined with IOL dislocation at the Department of Ophthalmology of Xiangya Hospital from January 2004 to December 2020 were enrolled. The patients received vitreoretinal surgery and reposition of IOL by scleral suturing. Medical records were reviewed to figure out the time and type of IOL dislocation. Preoperative and 1 year of postoperative best corrected visual acuity, intraocular pressure, corneal endothelial density, and complications of surgical management were analyzed.
resultsTen patients including 4 high myopia, 4 ocular contusion, and 2 who experienced IOL dislocation during the posterior capsulotomy were included in this study. Coexistence of IOL dislocation and vitreoretinal abnormalities occurred in patients with high myopia, ocular contusion, and capsulotomy. IOL dislocation happened in the vitreoretinal surgery in patients with high myopia or intraoperative capsulotomy. IOL dislocation occurred preoperatively in patients with ocular contusion. IOL capsular bag complex dislocation and out-of-the-bag IOL dislocation were found in 4 and 6 patients, respectively. Surgical relocation of dropped IOL and repair of vitreoretinal disease improved the best corrected visual acuity from preoperative 1.79±0.39 to postoperative 1.13±0.45 (
conclusionsDislocation of IOL may be concurrent with vitreoretinal disease. High myopia, blunt contusion, and capsulectomy might be the risk factors for intraocular lens dislocation. The surgical technique used in the present study is successful in manipulating these disorders with optimal functional results and less severe complications.
