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
purposeTo compare the outcomes of scleral wound suturing and non-suturing in 23-gauge vitrectomy combined with cataract phacoemulsification on eyes with severe proliferative diabetic retinopathy.
methodsThis retrospective cohort study enrolled patients with proliferative diabetic retinopathy who underwent a 23-step vitrectomy combined with cataract phacoemulsification. Scleral wounds were either sutured or left unsutured in sutured group and unsutured group, respectively. All patients were monitored for 6 months, undergoing slit-lamp examination, intraocular pressure measurement, fundus examination, and vision assessment.
resultsA total of 79 eyes were enrolled in sutured group and 85 eyes in unsutured group. Both groups were well-matched for factors such as age, sex, intraocular pressure (IOP), hypertension, diabetes duration, HbA1c levels, visual acuity, retinal detachment, neovascular glaucoma, and preoperative pan-retinal photocoagulation. Despite scleral incision sutures in sutured group, there was no significant difference in surgical time between the groups. Silicone oil and gas tamponade were similarly used, and no significant differences in postoperative complications were found, except that scleral suturing potentially exacerbated conjunctival or scleral scarring. Sutured group had a lower incidence of hypotony, though IOP was not significantly different between groups after one week. For silicone oil tamponade, IOP was comparable between groups, while for gas tamponade, early postoperative IOP was significantly lower in unsutured group. The incidence of postoperative hypotension was higher in unsutured group with gas tamponade. Visual acuity recovery showed no disparity between the groups.
conclusionFor patients with proliferative diabetic retinopathy undergoing vitrectomy combined with cataract surgery, scleral incision suturing appeared to be more effective in maintaining intraocular pressure in the early stage, especially for those who had gas as the vitreous tamponade. However, this might worsened conjunctival or scleral scarring. There were no significant differences observed in postoperative complications and visual acuity recovery between patients with and without scleral wound suturing.
