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
introductionAcross the globe, traditional medicine, particularly herbal remedies, is a cornerstone of healthcare. While the medicinal uses of ferns are widely recognized globally, their therapeutic potential in Uganda remains significantly underexplored compared to higher plants. This limited research creates a critical gap in our understanding of the medicinal capacities of ferns, leading to their neglect in drug development. The main aim of this study, therefore, was to document the medicinal fern species and their uses in communities bordering Kalinzu Central Forest Reserve (KCFR).
methodsAn ethnobotanical survey was conducted for 3 months (October, November, and December), 2024 in 20 villages bordering Kalinzu Central Forest Reserve (KCFR) in Kyamuhunga. The study utilized a semi-structured questionnaire and face-to-face interviews with 71 key informants to collect data on the use of ferns in herbal medicine. The questionnaire data was analyzed using various ethnobotanical indices, including Relative Frequency of Citation (RFC), Use Value (UV), Relative Importance (RI), Fidelity Level (FL), Informant Consensus Factor (ICF), and Combination Use Diversity Index (CUDI).
resultsSix fern species were documented for use in herbal medicine by communities around KCFR, and Pteridium capense was the most cited species. The use value (UV) index was highest for P. capense (0.72). The informant consensus factor (ICF) was highest for musculoskeletal illnesses (1.00), and the fidelity level (FL) was highest for Hypolepis sparsisora for treating burns (100%). Fronds were the most used part of the ferns in herbal medicine (76.06%), and dermal (smearing and rubbing) was the most common route of administration (57.75%).
conclusionsMedicinal ferns are an important component of traditional herbal medicine in communities bordering KCFR. The study documented different medicinal fern species for treating various ailments in communities bordering KCFR. Pteridium capense was the most frequently cited species, used to treat various illnesses. These findings highlight the significant ethnobotanical knowledge of the local communities and suggest that further research into the pharmacological properties of these fern species, especially P. capense, is warranted. Further research should characterize and elucidate bioactive compounds responsible for such therapeutic values.
