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
backgroundIntervertebral disc degeneration (IVDD) is a major cause of low back pain, characterized by mitochondrial dysfunction and impaired mitophagy in nucleus pulposus-derived mesenchymal stem cells (NPMSCs). Sirtuin 1 (SIRT1), a key regulator of mitochondrial quality control, is downregulated in degenerated discs. Salidroside (Sal), a natural compound from Rhodiola rosea, has shown potential in enhancing mitophagy, but its mechanism in IVDD remains unclear.
methodsUsing network pharmacology, molecular docking, and dynamics simulations, we identified SIRT1 as a key target of Sal. Human and rat NPMSCs were isolated and treated with tert-butyl hydroperoxide (TBHP) to induce degeneration. In vitro assays included CCK-8, EdU, SA-β-Gal, JC-1, Western blot, immunofluorescence, and transmission electron microscope (TEM). An in vivo rat IVDD model was established via needle puncture and treated with Sal and/or the autophagy inhibitor 3-MA. Histological, immunohistochemical, and imaging analyses were performed to evaluate IVDD.
resultsSal bound stably to SIRT1 and activated SIRT1/FOXO3 pathway, promoting mitophagic flux, reducing reactive oxygen species accumulation, and suppressing apoptosis in NPMSCs. SIRT1 knockdown or 3-MA treatment abolished Sal's protective effects. In vivo, Sal treatment preserved disc height, reduced apoptosis, and enhanced mitophagy, while 3-MA exacerbated degeneration.
conclusionsSal attenuates IVDD by activating SIRT1/FOXO3-mediated mitophagy, restoring mitochondrial homeostasis, and reducing NPMSCs apoptosis. These results suggest that the activation of the SIRT1/FOXO3-mitophagy axis may represent a potential therapeutic strategy for mitigating IVDD.
