The Glucagon-Like Peptide-1 (GLP-1) Receptor Agonist Liraglutide Regulates Sirtuin-1-Mediated Neutrophil Extracellular Traps to Improve Diabetes-Induced Bone Metabolism Imbalance.

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: Diabetes mellitus (DM) is a chronic metabolic disorder that disrupts normal bone remodeling. Objectives: This study aimed to investigate how the glucagon-like peptide-1 (GLP-1) receptor agonist liraglutide (LIR) addresses bone metabolism imbalances induced by type-II diabetes. Methods: Type-II diabetic rat models were established through a single intraperitoneal injection of streptozotocin (STZ). Blood glucose levels were measured using a blood glucose meter, and insulin levels were assessed using an assay kit. Bone formation markers [alkaline phosphatase (ALP), osteocalcin (OCN), and procollagen I N-terminal propeptide (PINP)] and bone resorption markers [tartrate-resistant acid phosphatase (TRACP) and CTX-1] were monitored using assay kits. Bone marrow mesenchymal stem cells (BMSCs) were cultured in vitro under high-fat and high-glucose (HFHS) conditions to mimic diabetic bone metabolism dysregulation. Neutrophil extracellular traps (NETs) formation was examined through immunofluorescent staining and Western blot analysis. Results: Liraglutide was found to reduce STZ-induced NETs formation, as indicated by decreased expression of cit-H3 by 36.90% - 53.57%, myeloperoxidase (MPO) by 55.81% - 65.12%, NE by 53.95% - 65.17%, and PAD4 by 46.81% - 63.83%, alongside increased Sirtuin-1 (SIRT1) expression in femur tissue (70.71% - 91.19%). In vitro, LIR enhanced osteogenesis and inhibited apoptosis, effects that were partially reversed by SIRT1 knockdown. Additionally, SIRT1 knockdown partially restored LIR-induced reductions in oxidative stress, inflammation, and NETs formation. Conclusions: LIR mitigates diabetes-induced bone metabolism imbalance by inhibiting NETs formation through SIRT1 mediation.
