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: Paraspinal muscle degeneration, particularly fat infiltration, is a prominent feature of adult degenerative scoliosis (ADS), which impairs spinal stability, accelerates disease progression, and contributes to poor clinical outcomes. However, the underlying molecular mechanisms remain unclear. This study aims to investigate the role of the hsa_circ_0006156/miR-122-5p/PPARA regulatory axis in this process. Methods: Paraspinal muscle fat infiltration was assessed by MRI in ADS patients and 40 age-matched controls. HE staining, Oil Red O staining, and RT-PCR were used to evaluate muscle structure and gene expression. Overexpression of hsa_circ_0006156 and inhibition of miR-122-5p were performed in primary multifidus muscle cells. Western blot and dual-luciferase reporter assays were used to verify the regulatory pathway. Results: Paraspinal muscle fat infiltration was significantly increased in ADS patients and showed clear asymmetry. hsa_circ_0006156 was downregulated on the concave side. Its overexpression reduced lipid accumulation, downregulated adiponectin and perilipin, and increased PPARA expression. Bioinformatics analysis and luciferase assays confirmed miR-122-5p as a direct target of hsa_circ_0006156, and PPARA as a downstream gene of miR-122-5p. Inhibiting miR-122-5p reduced fat accumulation and increased PPARA expression. Co-transfection assays showed that hsa_circ_0006156 regulates lipid metabolism by sponging miR-122-5p and releasing its inhibition on PPARA. Conclusion: Paraspinal muscles in ADS patients show marked fat infiltration with lateral asymmetry, especially on the concave side. hsa_circ_0006156 regulates lipid metabolism through the miR-122-5p/PPARA axis and reduces fat deposition, providing a potential molecular target for early diagnosis and intervention in ADS-related muscle degeneration.
