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
introductionTo develop an innovative preclinical full-thickness macular hole (FTMH) model using porcine eyes and to evaluate the feasibility of decellularized human corneal lenticule (hCL) as a novel bio-graft for macular hole closure.
methodsTwenty-five eyes (n = 25) were obtained from pigs euthanized for food consumption and transported to the laboratory within 3 h. Surgical procedures were performed by the same experienced vitreoretinal surgeon using a Leica Proveo microscope (Proveo 8, Leica Microsystems Inc.) with integrated intraoperative optical coherence tomography (iOCT) technology. After core vitrectomy and posterior vitreous detachment, FTMH was induced using diathermy and a vitrectomy probe. hCLs (thickness 100-120 µm), collected from refractive surgery patients, were decellularized and introduced into the vitreous cavity. With the aid of a viscoelastic agent for stability, hCLs were positioned into the FTMH using microsurgical forceps. Placement and integration were evaluated by iOCT and immunofluorescence (IF) analysis.
resultsOCT images and IF analysis confirmed the successful creation of FTMHs ex vivo in porcine eyes, demonstrating the feasibility of hole induction in an ex vivo model. Preliminary OCT and IF analyses showed the successful implantation of decellularized hCLs at the FTMH site, which were correctly positioned in the subretinal space between the choroid and the retinal pigment epithelium.
conclusionsOur preliminary results suggest that decellularized hCLs can be successfully implanted to close FTMHs in our preclinical ex vivo model of study, paving the way for future research into bioengineered hCLs for therapeutic purposes.
