Epimedin B protects against bone loss and inflammation in diabetic osteoporosis rats by regulating OPG/RANKL pathway.
Article in Journal of orthopaedic surgery and research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundDiabetes is a common disease contributing to osteoporosis. Epimedin B (EB), a major ingredient of Herba Epimedii, has been found to be effective in preventing osteoporosis in mice. However, the potential of EB to ameliorate diabetic osteoporosis (DOP) remains elusive. In this study, our goal is to investigate the functions and underlying mechanisms of EB in the progression of DOP.
methodsA DOP rat model was established via a high-fat diet combined with intraperitoneal injection of streptozotocin (STZ). DOP rats were daily administered with EB or vehicle via intragastric administration for 8 weeks. Body weights and blood glucose levels were measured every 4 weeks during the drug administration period. Blood samples and femoral tissues were collected for further analysis. Bone parameters and bone histopathological changes were detected. Bone formation and resorption markers as well as inflammatory factors were detected using enzyme-linked immunosorbent assay kits. Reverse-transcription quantitative polymerase chain reaction and western blotting were conducted to measure the expression of osteoprotegerin (OPG) and Rev-Erbα, receptor activator of NF-κB ligand (RANKL).
resultsEB improved weight loss and lowered blood glucose of DOP rats. EB promoted the formation of bone trabeculae and altered several bone microstructure parameters in DOP rats. EB ameliorated improved bone structure, restored histological abnormalities of femoral bone, and reduced the number of bone marrow adipocytes in DOP rats. EB inhibited excessive bone resorption and inflammation and increased bone formation in DOP rats. EB regulated the OPG/RANKL axis in DOP rats.
conclusionEB attenuates STZ-induced DOP in rats by maintaining the balance between bone formation and resorption and inhibiting inflammation through regulating the OPG/RANKL axis.
