Chitosan nanoparticles-encapsulated cannabis extracts and their antimicrobial potential against skin pathogens.
Article in Frontiers in medicine, 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
Cannabis compounds are well-known for their therapeutic applications in the treatment of various health issues. These substances, mainly cannabinoids, are known for their antimicrobial properties and ability to interact with various cells through endocannabinoid receptors. However, the limitations of cannabis extract, particularly its viscosity, stickiness, and low bioavailability when applied topically, limit its use in dermatology. To enhance topical applications for treating bacterial infections and dermatophytosis, cannabis extracts were encapsulated in chitosan nanoparticles, an easily accessible and cost-effective. Cannabis extracts were prepared from three cannabis strains differing in content of major cannabinoids, namely Chocolope (THCA-A), Jonas 1 (CBDA), and Hemp G (CBGA), and subsequently were encapsulated in chitosan nanoparticles. The resulting particles were characterized, and antimicrobial and cytotoxic activity was evaluated. The mean size of particles ranged from 89.1 ± 24.8 nm for empty nanoparticles to 355.6 ± 101.6 nm for particles containing Hemp G extract. Considering the extract:chitosan ratio (1:10 w/w, 1:20 w/w respectively) and the encapsulation efficiency (EE) range from 44.65 ± 4.39% to 94.44 ± 0.93%, total amount of extracts encapsulated in chitosan nanoparticles ranged from 2.96 ± 0.05 to 5.61 ± 0.19% in 1 g of chitosan nanopowder. Most significant antimicrobial effect was observed against the fungi
