Ethnobotanical study of wild edible plants in Pa Tio District, Yasothon Province, Thailand.

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
backgroundWild edible plants (WEPs) are integral to food security, nutrition, healthcare, and cultural identity in rural northeastern Thailand. However, systematic ethnobotanical documentation of WEP diversity, cultural importance, and economic roles in Pa Tio District, Yasothon Province, has been limited. This study provides the first comprehensive assessment of WEPs in the district, highlighting their multifunctional roles within local food systems, traditional medicine, and livelihoods.
methodsEthnobotanical data were collected through semi-structured interviews, group discussions, and guided field walks with 50 Lao-Isan informants selected using purposive and snowball sampling. Recorded species were categorized by use, and quantitative indices—Cultural Food Significance Index (CFSI), Fidelity Level (FL), and Informant Consensus Factor (ICF)—were applied to evaluate cultural prominence and medicinal consensus. One-year market surveys were conducted to estimate the economic value (EV) of traded WEPs, while cross-regional similarity was assessed using the Jaccard Similarity Index.
resultsA total of 100 WEP species from 48 families were recorded, with vegetables and fruits dominating local diets. CFSI values showed strong differentiation among taxa; Ipomoea aquatica Forssk. had the highest value (140,625.00), reflecting its role as a daily staple. FL values ranged from 8.70% to 80.00%, and consistently high ICF values (0.857–0.955) indicated strong agreement among informants and a well-structured traditional knowledge system. Fifty-one species were traded in local markets, with Limnophila geoffrayi Bonati generating the highest annual economic return. Species similarity with neighboring regions was low (8.6–14.8%), underscoring pronounced local specificity.
conclusionWEPs in Pa Tio District form a resilient biocultural system linking food security, health, cultural continuity, and livelihoods. Supporting community-based management and sustainable use is essential for strengthening rural food systems and biodiversity conservation.
