Knowledge of the risks associated with being underweight and body shape differences among young Japanese women: a cross-sectional study.
Article in BioPsychoSocial medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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
backgroundIn Japan, approximately 20% of young women are underweight, a rate higher than that of other developed countries. For women, being underweight at a young age has been associated with amenorrhea, eating disorders, osteoporosis, and adverse pregnancy outcomes. We investigated young women's knowledge of these risks and associated factors.
methodsA web-based survey was conducted among 984 Japanese women aged 18-29 years. The survey included questions about actual body weight, perceived healthy weight, body image, eating disorder tendency, knowledge of various risks and factors associated with being underweight, and sources of this knowledge. Participants were divided into underweight (< 18.5 kg/m
resultsAmong the participants, 31.5% were underweight (BMI < 18.5 kg/m
conclusionsYoung Japanese women had insufficient knowledge about the adverse pregnancy outcomes associated with being underweight. Underweight women are not less aware of the health risks and associated factors associated with underweight than normal-weight women. The body shape of young women may not be influenced by their knowledge of health issues associated with being underweight.
