Article in Veterinary medicine and science, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundTissue engineering utilizing hydrogels and scaffolds composed of organic and synthetic materials has emerged as a promising approach for bone repair. Chitosan, a biocompatible natural polymer, supports bone healing and possesses antibacterial and antioxidant properties. Fennel (Foeniculum vulgare), known for its traditional use in treating osteoporosis in females, exhibits phytoestrogenic properties.
objectivesThis study investigated the osteogenic differentiation of mesenchymal stem cells (MSCs) cultured within chitosan hydrogels incorporating fennel seed extract.
methodsFourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy (SEM) were employed to characterize the chitosan films containing fennel extract. MSCs were isolated from ovine foetal bone marrow and subjected to various concentrations of fennel hydroalcoholic extract and hydrogels containing these extracts. Cell viability was assessed using the MTT assay. Following osteoblast differentiation, gene expression of osteogenic markers (ALP, Runx2 and COL1A1) was evaluated using real-time PCR, alongside assessments of calcium deposition, alkaline phosphatase activity and ALP expression. Alizarin red staining was performed to quantify mineralized matrix deposition.
resultsThe MTT assay revealed that the 0.5% extract treatment group significantly enhanced MSC proliferation. Notably, MSCs cultured on the chitosan film containing 1% fennel extract demonstrated increased numbers of hydroxyapatite deposits, elevated ALP activity and calcium content and upregulated expression of osteogenic genes (ALP, Runx2 and COL1A1). Acridine orange/ethidium bromide staining confirmed the non-toxicity of the extract in all treatment groups.
conclusionThese findings demonstrate that chitosan hydrogels incorporating fennel seed extract can effectively induce osteogenic differentiation of MSCs, highlighting their potential as a promising strategy for bone tissue regeneration.
