Body mass index, nutritional knowledge, and eating attitudes in dancer and non-dancer students.
Article in BMC research notes, 2026. 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
backgroundThis cross-sectional comparative study examined differences in body mass index (BMI), nutritional knowledge, and eating behaviors between dancer and non-dancer university students. Given the physical and aesthetic demands of dance, understanding potential differences in health-related characteristics in this population is of particular importance.
methodsSeventy female undergraduates (35 dancers and 35 non-dancers, aged 17-22 years) were recruited. Height, weight, and BMI were measured using the InBody 970 analyzer. Nutritional knowledge was assessed using the Chinese version of the General Nutrition Knowledge Questionnaire (C-GNKQ), and disordered eating risk was evaluated using the Eating Attitudes Test-26 (EAT-26)©. Group differences were analyzed using independent t-tests, with effect sizes (Cohen's d) calculated to estimate the magnitude of differences.
resultsDancers were significantly taller than non-dancers (P = 0.003, d = 0.74) and had a lower BMI (P = 0.023, d = 0.82). No statistically significant difference was observed in overall C-GNKQ scores (P = 0.128, d = 0.37), although dancers scored higher in the dietary knowledge subscale (P = 0.037, d = 0.52). EAT-26© scores were higher in dancers, but the difference was not statistically significant (P = 0.147, d = 0.35). Additional Spearman correlation analyses revealed no significant associations among BMI, C-GNKQ scores, and EAT-26© scores (P > 0.05).
