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
backgroundDelayed wound closure and non-healing wounds represent a problematic condition with health burden and an economic challenge. Therefore, different strategies have been developed, including skin tissue engineering, which aims to stimulate and support the wound healing process. In this study, the potential of graphene oxide (GO) and chitosan (CTS) biomaterial composite, with and without fetal bovine serum (FBS), was investigated to induce a full-thickness skin wound repair in rats.
methodsThe GO-CTS composite was characterized using X-ray diffraction, transmission electron microscopy, and Fourier transforms infrared. Cytocompatibility was evaluated via an MTT assay with human endothelial cells (ECs) and mouse embryonic fibroblasts (MEFs) in vitro. The in vivo wound regeneration potential was assessed by creating an 8 mm full-thickness circular skin defect on the dorsal surface of the rat. The defects were randomly divided into control, GO-CTS, FBS, and GO-CTS/FBS groups, and were monitored grossly and histologically at days 7 and 21 after wound induction.
resultsThe GO-CTS material demonstrated high cytocompatibility, with cell viability recorded at 99.2% ± 5.7% for ECs and 110.5% ± 3.9% for MEFs. The highest proliferation rates were observed in the FBS (118.2% ± 2.1%) and GO-CTS/FBS (121.4% ± 4.4%) groups. In vivo, wound closure rates on day 21 were 85.5% ± 0.56% for GO-CTS, 87.5% ± 1.75% for FBS, and 91.5% ± 1.03% for GO-CTS/FBS, all significantly higher than the control group. Additionally, neovascularization, epithelialization, collagen deposition, and granulation tissue formation were more prominent in the treated groups, with skin appendages observed in the GO-CTS/FBS group.
conclusionGO-CTS nanosheets with FBS represent a promising biomaterial for skin tissue engineering and can effectively initiate and support wound healing.
