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
BACKGROUND AND
objectivesDescemet's stripping endothelial keratoplasty (DSEK) has emerged as the preferred method for posterior lamellar keratoplasty, as it enables the replacement of the compromised host endothelium with a viable donor lamella. The objective of this study was to assess the impact of DSEK on surgical outcomes and visual acuity.
methodsThe research was carried out from November 2019 to October 2021, encompassing a sample of 18 patients (18 eyes) who satisfied the inclusion criteria for DSEK. The pre-operative evaluation was performed once before the surgery, while post-operative evaluations were conducted at one, three, and six months after the surgical intervention. The main variables assessed in this study encompassed demographic characteristics, visual acuity, surgical techniques, and surgical complications employed during the surgical procedure. The collected data were statistically analyzed using IBM SPSS software version 21 (IBM Corp., Armonk, NY, USA).
resultsPatients in the study ranged in age from 25 to 70, with a mean age of 53.16 ± 14.19 years. The participants were 61% male and 39% female. The main reasons for DSEK use were pseudophakic bullous keratopathy (61%) and post-penetrating keratoplasty (PK) graft failure (17%). The other indications were aphakic bullous keratopathy (11%), bullous keratopathy with cataracts (5%), and Fuchs's endothelial dystrophy (5%). The study included 18 eyes: 14 eyes underwent DSEK, two underwent DSEK with small-incision cataract surgery (SICS) and posterior chamber intraocular lens (PCIOL) implantation, and two underwent DSEK with scleral-fixated FIL. A significant improvement in best-corrected visual acuity (BCVA) was observed at six-month follow-up (0.73 ± 0.37 vs. 1.73 ± 0.59 logMAR pre-operatively). During donor cornea dissection, buttonholing was the main concern, occurring 11% of the time. Descemet's perforation and donor preparation thickness variations were also observed. Reverse donor unfolding, incomplete DM stripping, and donor button displacement were quickly addressed and managed. Post-operative graft failure occurred in 22% of cases, while acute graft rejection occurred in 11%. Graft dislocation, pupillary block, and secondary glaucoma each had a 5% prevalence.
conclusionDescemet's stripping endothelial keratoplasty is a safe and effective treatment for corneal endothelial disorders, particularly in cases where scarring is not present. Surgical skills are essential to achieving the desired results. Descemet's stripping endothelial keratoplasty is favored over conventional keratoplasty for endothelial dysfunction due to its technical advantages and manageable risks. Our research demonstrates a significant improvement in visual acuity through DSEK. Despite manageable post-operative complications, it is vital to educate patients and medical professionals on surgical complexities. Descemet's stripping endothelial keratoplasty appears promising for the treatment of endothelial disorders, but its long-term implications must be studied.
