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
objectiveTo evaluate the effects of capsular tension ring (CTR) implantation on postoperative visual quality, intraocular lens (IOL) decentration, and tilt, as well as to evaluate its effects on postoperative visual acuity, refraction, IOL positional stability, and other ocular measurements.
methodsThis retrospective study included 218 patients with highly myopic cataract (218 eyes). The patients were divided into an experimental group (CTR+IOL, 121 eyes) and a control group (IOL only, 97 eyes) according to surgical protocols. All patients underwent standard cataract surgery, and the experimental group received CTR implantation during surgery. Preoperative and post-operative assessments at 1, 3, and 6 months included best-corrected visual acuity (BCVA), uncorrected visual acuity (UCVA), refraction, IOL decentration, tilt angle, anterior chamber depth (ACD), intraocular pressure (IOP), endothelial cell density (ECD), modulation transfer function (MTF), coma aberration, and visual quality indicators (disability glare index (DLI) and quality of vision index (QVI)).
resultsSix months after surgery, ACD, ECD, and improvements in IOL decentration, as well as horizontal and vertical IOL tilt angles and MTF, were significantly better in the experimental group than in the control group (all P<0.05). Coma aberration was significantly lower in the experimental group compared to the control group (P<0.05). There were no significant differences in visual acuity (BCVA, UCVA) or refractive errors (REs) between the groups. However, the experimental group showed greater improvement in visual quality assessment (DLI, QVI). Additionally, a significant interaction between treatment protocol and age was observed for ECD and horizontal IOL tilt.
conclusionCTR implantation improves postoperative visual outcomes in highly myopic cataract patients, particularly by reducing IOL decentration and tilt. It enhances visual quality, promotes IOL positional stability, and improves key ocular physiological indicators.
