Changes of diabetic macular edema post vitrectomy in patients with proliferative diabetic retinopathy.

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
aimTo investigate the change of diabetic macular edema (DME) post vitrectomy and its risk factors.
methodsThis retrospective study included 365 eyes of 330 patients who underwent vitrectomy for proliferative diabetic retinopathy (PDR) with gradable optical coherence tomography (OCT) imaging from January 2018 to March 2022. The incidence of post vitrectomy DME (PV-DME) was defined as patients with a central retinal thickness (CRT) >300 µm by OCT among patients without preoperative DME.
resultsThe cumulative incidence of PV-DME at 3mo was 40.1% (89/222), with its majority subtype of single diffused retinal thickening (66.2%) followed by single cystoid macular edema (27.0%). Multivariate Cox regression analysis indicated that a thicker preoperative CRT [hazard ratio (HR)=1.01, 95% confidence interval (CI) 1.00-1.02] and intraoperative internal limiting membrane peeling (HR=3.18, 95%CI 1.85-5.47) were associated with the presence of PV-DME, while intraoperative intravitreal injection of triamcinolone acetonide (HR=0.28, 95%CI 0.13-0.57) was protective against PV-DME. In eyes with preoperative DME (
conclusionPV-DME is a very common postoperative complication in patients with PDR. Triamcinolone acetonide could prevent its formation. Attention should be paid to patients with a thicker preoperative CRT and internal limiting membrane peeling.
