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
Recent advancements in wound care have explored the use of biological dressings, including fish skin, due to its rich collagen content and bioactive components that promote healing. This study aimed to evaluate the effectiveness of fresh and lyophilized Nile tilapia skin in enhancing full thickness skin wound healing in donkeys. Nile tilapia skin was collected, thoroughly washed, lyophilized, and sterilized. Five female donkeys were used in the study, each receiving three full-thickness skin wounds (2 cm x 2 cm) on each side of the back after aseptic preparation and local anesthesia, resulting in a total of six wounds per animal. The wounds were assigned to three groups: control (treated with saline), fresh fish skin, and lyophilized fish skin. Macroscopic wound assessment was performed and skin samples were collected on days 14 and 28 for histological examination using hematoxylin and eosin (H&E) and Crossman's trichrome staining. Results revealed that treatment with lyophilized fish skin significantly accelerated wound contraction and epithelialization compared to the control and fresh fish skin-treated groups. On day 14, wound contraction rates were 43.57% ± 0.87 for lyophilized fish skin, 41.32% ± 0.26 for fresh fish skin, and 32.48% ± 0.39 for the control. By day 28, contraction rates increased to 74.37% ± 0.77, 66.92% ± 0.31, and 56.88% ± 0.73, respectively. Histological analysis showed enhanced collagen deposition and angiogenesis in the lyophilized fish skin group. In conclusion, lyophilized Nile tilapia skin is a promising and cost-effective biomaterial for enhancing wound healing, offering a practical solution for field veterinarians in low-resource settings.
