Article in PeerJ, 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
Background: Probiotics are composed of trillions of microorganisms, mainly located in the gastrointestinal tract (GIT), which play vital roles in digestion, immunity, and overall well-being. They help maintain gut health and prevent various gastrointestinal disorders. Despite the widespread use of probiotics in developed countries, such as North America and Western Europe, little is known about their use in Saudi Arabia. This study aimed to assess the knowledge, attitudes, and factors influencing probiotic awareness among the Saudi public to support healthier dietary choices. Materials: A cross-sectional study using a structured questionnaire titled "Public Knowledge and Perception of Probiotics" was conducted among Saudi residents aged 18 years and older from July to October 2024. With a type I error rate of 5% (α = 0.05) and 80% power, the required sample size was 269; ultimately, 286 individuals participated in the study. Data were analyzed using the Statistical Package for the Social Sciences version 27 (IBM). Results: The majority of the 286 participants were female (79%) and over 30 years old (54.9%). Awareness of probiotics was moderate (mean score: 5.2; 65%), with yogurt being the most recognized source (95%). Participants generally had positive perceptions (mean score: 3.74 ± 0.60), although barriers such as limited knowledge (56.2%) and high cost (3.28 ± 1.09) were reported. Probiotic use was noted in 54.5% of the respondents, with 71.2% preferring natural sources. Usage was significantly associated with demographic factors, including age ( Conclusion: While awareness and positive perceptions of probiotics are growing among the Saudi population, challenges such as knowledge gaps, affordability, and limited advertising persist. To promote probiotic use and improve public health outcomes, it is crucial to enhance public health education through schools and community programs, improve affordability
