Anatomical, Functional, and Prognostic Results of Vitrectomy in Epiretinal Membranes Secondary to Retinal Vein Occlusions.

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
introductionWe investigated the anatomical and functional results of vitrectomy associated with the peeling of secondary epiretinal membranes (ERM) in patients with retinal vein occlusion (RVO) and determined the prognostic factors of surgical outcomes.
methodsThis retrospective, multicenter, observational study included 50 patients with RVO who underwent vitrectomy with ERM removal between July 2012 and February 2021. Visual acuity (VA) and central macular thickness (CMT) were investigated up to 3 years. Univariate analysis identified the predictive factors associated with functional and anatomical outcomes.
resultsFifty eyes from 50 patients (62% with central RVO) were included. The mean VA of 0.9 ± 0.7 logMAR preoperatively improved to 0.5 ± 0.5 logMAR after 24 months (p = 0.01). Anatomically, the mean preoperative CMT was 501 ± 168 μm, decreasing to 348 ± 108 μm at month 24 (p = 0.008). By 36 months, VA had improved or stabilized in 90% of the eyes, whereas CMT had been reduced by at least 20% from baseline in 80% of the eyes. A lower number of intravitreal injections (IVI) were required after vitrectomy. Worse preoperative VA, absence of preoperative panretinal photocoagulation, and postoperative use of adjunctive IVI were associated with VA recovery. Higher baseline CMT and the use of preoperative dexamethasone injections were associated with an improvement in CMT.
conclusionVitrectomy for ERM secondary to RVO was effective in improving VA and recovering CMT for up to 3 years and reduced the number of IVIs.
