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
Introduction: Platelet-rich fibrin is an autologous biomaterial that is rich in platelets and various growth factors, has good biocompatibility, and has significant application potential in tissue repair and regeneration. Aim: To explore the effect of platelet-rich fibrin (PRF) on the repair and healing of chronic refractory wounds in rats by regulating the Wnt/β-catenin (β-catenin) signalling pathway. Material and methods: Full-thickness skin defect open wounds were established on the backs of 50 male SD rats. Results: In comparison with the normal control group, the wound healing rate, CD34-positive cell ratio, and Wnt1, β-catenin, and c-myc protein expression levels of rats in the model group were significantly reduced at each time point; serum TNF-α, IL-1β, IL-6 levels, and GSK-3β protein expression levels were significantly increased. The granulation tissue was severely damaged and infiltrated by a large number of inflammatory cells. The collagen fibres were loosely arranged and unevenly distributed. In comparison with the model group, the wound healing rate, CD34-positive cell ratio, and Wnt1, β-catenin, and c-myc protein expression levels of rats in the PRF group and positive control group at each time point were significantly increased. Conclusions: PRF can promote the repair and healing of chronic refractory wounds in rats by inhibiting ulcer surface inflammation and promoting collagen fibre deposition and angiogenesis. Its mechanism of action may be concerned with the activation of the Wnt/β-catenin signalling pathway.
