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
Optimal healing of full-thickness skin wounds remains a clinical challenge. While current skin substitutes aid burn wound management, there is still a need to effectively minimize scarring. Therefore, we developed type I collagen scaffolds with covalently bound ReGeneraTing Agent (RGTA) OTR4120 (OTR), a synthetic heparan sulphate analogue resistant to glycanase degradation (Col I + OTR). To further stimulate skin regeneration, collagen scaffolds with and without OTR4120 were subsequently loaded with sonic hedgehog (SHH), a key effector molecule in embryogenesis. The presence of OTR4120 and SHH in scaffolds was biochemically and histologically confirmed after crosslinking and sterilization. SHH was found deeper into collagen scaffolds in the presence of OTR4120. Addition of SHH to scaffolds showed lower expression of M1-like cell surface markers, while Col I + OTR significantly enhanced IL-10 production. The potential of OTR4120 in wound healing was further evaluated in vivo using a rat full-thickness wound model over 28 days. By day 14, macroscopic images revealed that OTR-treated wounds better maintained the original wound shape. Histological analysis showed increased blood vessel formation, fewer scaffold remnants and more contiguous sebaceous glands in the granulation tissue with Col I + OTR scaffolds. This study demonstrates that OTR4120 could be a promising addition to acellular skin substitutes for improving acute wound healing.
