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
Hypertrophic scar (HS) is one of the most common complications of skin injuries, with a lack of effective therapeutic approaches to date. Most current research has focused on the dysfunction of hypertrophic scar fibroblasts (HSFBs) and dermal vascular endothelial cells (HDVECs), neglecting the crucial role of the inflammatory microenvironment that causes them to be abnormal. In this study, we first discovered and validated that the S100A8/9 specific inhibitor Paquinimod could inhibit macrophage polarization toward M1, and further suppress the proliferation, migration, collagen formation, and angiogenesis of HSFBs and HDVECs in vitro. This mechanism has also been validated in a rat model of HS. Then, we developed a good biocompatibility and penetrability Paquinimod-Hydrogel Hybrid Microneedle Array Patch (PHMAP) for HS treatment. With the advantages of excellent penetrability, surface sealing, sustained release, and precise uniform distribution, PHMAP exhibited superior therapeutic efficacy over intravenous and intradermal injections. These results suggest that PHMAP can be a promising and advanced solution for HS prevention and therapies.
