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
Liver regeneration from acute injury is well-studied, and various factors and pathways are known to be involved. Circular RNAs (circRNAs) are emerging as critical regulators in liver pathophysiology, yet their roles in liver regeneration remain unclear. Here, we characterized a circular RNA, circLAMC1, which was highly upregulated in rats after partial hepatectomy (PH). Overexpression of circLAMC1 promoted liver cell proliferation in vitro. Further mechanistic studies revealed that circLAMC1 interacted with the microRNA miR-138-5p, and that miR-138-5p directly targeted Gnai2. While miR-138-5p mimics or Gnai2 knockdown repressed the proliferative effects mediated by circLAMC1, inhibition of miR-138-5p or Gnai2 upregulation enhanced liver cell proliferation. In vivo, AAV9-mediated circLAMC1 overexpression in mice increased the liver/body weight ratio, reduced liver injury, and increased the number of hepatocytes after PH. Furthermore, circLAMC1 activated the ERK signaling pathway through the miR-138-5p/Gnai2 axis, ultimately upregulating cell cycle proteins. Collectively, our data reveal a specific role for circLAMC1 in liver regeneration and provide a potential regulatory target for promoting liver regeneration after injury.
