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
backgroundThe increasing popularity of marathon running in China highlights the need to better understand the dietary habits and nutritional needs of marathon runners to optimize performance and health outcomes. The study aimed to assess the dietary behaviors, nutritional knowledge, and running-specific nutritional practices of Chinese marathon runners as part of the China Marathon Nutrition Survey (CMNS).
methodsThis nationwide cross-sectional survey was conducted between January and December 2024. Participants were recruited via official websites, social media, and onsite events. A structured and pre-tested questionnaire, referred to as the
resultsA total of 5668 valid questionnaires were included in the analysis, comprising 77.6% male (39.8 ± 10.9 yrs) and 22.4% female (41.0 ± 9.7 yrs) runners, representing a wide distribution across age groups and performance levels. Nearly half of the runners (49.1%) of runners reported no specific dietary habits, while among those with dietary practices, 26.4% adhered to a high-carbohydrate diet. In terms of running-related nutrition, 23.3% of Chinese runners regularly or frequently used dietary supplements, and 31.7% used them occasionally before important races. Carbohydrate-loading strategies were adopted by 57.2% of runners prior to races. However, only 36.7% of participants met the recommended fluid intake (1500-1700 mL/day) set by the Chinese Nutrition Society. Higher nutrition knowledge significantly predicted adherence to recommended hydration practices (
conclusionThis study provides insights into the nutritional knowledge, dietary behaviors, and race-specific nutrition practices of Chinese marathon runners, offering important baseline data for improving endurance nutrition. Common issues were identified in daily macronutrient intake, hydration, and race-day fueling. These findings underscore the gaps between knowledge and practice, emphasizing the need for tailored nutrition education, particularly for recreational runners through race organizers or public platforms.
