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
Diabetes mellitus is one of the risk factors for periodontitis. Patients with diabetes mellitus possess higher prevalence of periodontitis, more severe periodontal destruction, yet the underlying mechanisms of action are not yet clear. Annexin A2 (ANXA2) is a calcium-dependent phospholipid-binding protein widely involved in membrane repair, cytokinesis, and endocytosis. In this study, we explore whether ANXA2 is one of the associative links between diabetes and periodontitis and find out its underlying mechanisms. Cellular senescence and mitochondrial functions (ROS, mitochondrial morphology, mitochondrial autophagy) were observed. We observed that ANXA2 expression was down-regulated in Periodontal ligament cells (PDLCs) under high glucose conditions. Furthermore, overexpression of ANXA2 delayed high glucose-induced cellular senescence and mitochondrial dysfunction. β-galactosidase activity and the mRNA levels of the senescence-relative genes(p21,p16) were decreased, mitochondrial fracture and ROS release were reduced, and the expression of mitochondrial autophagy-related proteins (LC3,p62,Parkin) was enhanced. expression was enhanced. Mechanistically, we demonstrated that it can regulate the AKT/eNOS signaling pathway by knockdown and overexpression of ANXA2 which was measured using Western blotting (WB) assay to measure the expression of eNOS, p-eNOS Ser1177, Akt and p-Akt Ser473 proteins in PDLCs. After that, we used AKT and eNOS inhibitors to demonstrate the protective effect of ANXA2 on PDLCs under high glucose conditions. The above results suggest that ANXA2 has an anti-aging protective effect, attenuates high glucose-induced cellular senescence in PDLCs, and maintains mitochondrial homeostasis. Therefore, it would be valuable to further explore its role in the link between diabetes and periodontitis in future experiments.
