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
BACKGROUND/
aimKeloids result from abnormal wound healing and are characterized by excess fibroblast activity, extracellular matrix (ECM) accumulation, and elevated collagen types. The contemporary research often relies on 2D cell cultures, which do not fully replicate keloid pathophysiology. Spheroid models offer a promising alternative. This study analyzed gene expression differences in keloid and normal skin tissues, evaluated mRNA expression from 2D cultures, and assessed spheroid viability as proof of concept. MATERIALS AND
methodsKeloid and normal skin samples were collected from patients with auricular keloids. The tissues underwent histological and immunohistochemical analyses, RNA extraction for RT-qPCR, and 2D and 3D cell culture. Spheroids were cultivated for 21 days and analyzed for morphology, viability, and histological staining.
resultsHistological analysis revealed mixed results, with higher mRNA levels of
conclusionKeloid gene and protein expression patterns varied among native tissue, 2D cultures, and 3D cultures. Keloid-derived spheroids displayed distinct histomorphological features compared with normal skin spheroids, suggesting that they may serve as more physiologically relevant models for future keloid research.
