1 · What the graph read from it

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.

2 · The registry

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 describe the long-term observations of the first human implantation of EndoArt, a synthetic endothelial implant, in a small cohort of patients with corneal edema secondary to endothelial dysfunction.

methodsThis retrospective case series analyzed 5 eyes from 5 patients who underwent EndoArt implantation, with a minimum follow-up of 12 months. Clinical outcomes, including corrected distance visual acuity and central corneal thickness, were evaluated pre- and postoperatively. Rebubbling procedures and any complications were recorded. Histological analysis was performed on 1 explanted corneal button.

resultsThe mean follow-up was 38.4 ± 20 months (range: 19-72 months). A reduction in mean central corneal thickness was observed, from 741.2 ± 88.3 μm preoperatively to 558.4 ± 72.7 μm postoperatively ( P < 0.001). Corrected distance visual acuity improved in 4 of 5 eyes, although not significantly overall ( P = 0.19). The mean number of rebubbling procedures was 2.8 ± 1.3 per eye. No serious implant-related complications were observed during the follow-up period. Histological findings showed fibrocellular tissue partially integrating the implant, which may contribute to graft adherence. Two patients with Fuchs dystrophy received the device as a primary procedure because of ethical or religious constraints regarding donor tissue.

conclusionsThis small pilot series of the first human EndoArt implantation observed a significant reduction of corneal edema over time and a favorable safety profile in select patients. Although these findings are encouraging, they should be interpreted with caution given the limited sample size. Larger, controlled studies are needed to better understand the safety, efficacy, and long-term outcomes of this synthetic implant.
