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: Heel pad degloving injuries represent one of the most challenging problems in lower-extremity reconstruction because durable soft-tissue coverage must withstand repetitive weight-bearing while minimizing infection, wound breakdown, and limb loss. Case Report: We report the use of staged fish-skin xenograft reconstruction as a limb-salvage strategy in a 24-year-old man who sustained a severe heel pad avulsion with multiple open fractures of the foot and ankle following an all-terrain vehicle accident. Initial management consisted of serial irrigation and debridement, fracture stabilization, and negative-pressure wound therapy; however, progressive heel pad necrosis resulted in a 22 × 15 × 0.5 cm full-thickness plantar soft-tissue defect extending to the calcaneus despite aggressive wound management. The patient was subsequently counseled regarding below-knee amputation due to the severity of soft-tissue loss but elected to pursue limb salvage following multidisciplinary discussion of reconstructive options. Three sequential applications of a fish-skin acellular dermal matrix (Kerecis) were performed over 8 weeks, resulting in progressive granulation tissue formation and development of a robust, well-vascularized wound bed suitable for definitive reconstruction. Subsequent full-thickness skin grafting to the heel and split-thickness skin grafting to the surrounding soft-tissue defects achieved complete wound closure without infection, graft loss, or wound breakdown. Hypertrophic scarring and contracture that developed during follow-up were successfully treated with fractional carbon dioxide laser therapy. At 1-year follow-up, the reconstructed heel remained completely healed without recurrent ulceration or infection, demonstrating durable soft-tissue coverage capable of tolerating the biomechanical demands of a weight-bearing plantar surface. Conclusion: This case demonstrates the potential role of staged fish-skin xenograft application as a biologically active reconstructive adjunct for wound-bed preparation and limb salvage in complex heel pad degloving injuries. In situations where immediate flap reconstruction is undesirable, and limb salvage remains the patient's goal, staged xenograft reconstruction may expand the reconstructive armamentarium while preserving ambulatory function.
