Assessment of nutrient intake, nutrition knowledge, and dietary habits by sports type among adolescent athletes at a physical education high school: a cross-sectional study.

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
objectiveThis study aimed to compare the nutrient intake, nutrition knowledge, and dietary habits of track-and-field (TF) and weight-class (WC) adolescent varsity athletes.
methodsThis cross-sectional study included 144 adolescent athletes (TF group, 76; WC group, 68) aged 15 to 18 years at a physical education high school in Seoul, South Korea. Their nutrient intake, dietary quality, nutrition knowledge, dietary habits, and weight control behaviors were assessed using food records and questionnaires.
resultsRegarding nutrient intake, the consumption of carbohydrates, including energy, was substantially lower than the sports nutrition recommendations in both groups. However, the overall diet quality, including the mean adequacy ratio and nutrient adequacy ratio for key micronutrients, was significantly higher in the WC group than in the TF group, with female WC athletes consuming significantly more energy than female TF athletes (P<0.05). For nutrition knowledge, both groups lacked overall sports nutrition understanding; however, the WC group scored significantly higher in dietary fat knowledge (P<0.05). As for dietary habits, despite having better meal quality, harmful weight control behaviors, including skipping breakfast (P<0.001) and fasting (P<0.05), were significantly more common in the WC group than in the TF group.
conclusionThe WC group, while showing better meal quality, practiced unhealthier dietary behaviors and weight control methods more often than the TF group. Additionally, both groups exhibited insufficient energy intake and lacked overall nutrition knowledge. Therefore, tailored sports nutrition education is urgently needed among South Korean adolescent athletes.
