Association of alternative healthy eating index with sleep quality among female students.
Article in BMC research notes, 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
objectivePoor sleep quality is common among university students and is linked to metabolic disorders, obesity, and mental health issues. Emerging evidence highlights the role of diet in regulating sleep, with healthier dietary patterns and specific foods shown to improve sleep quality. The Alternative Healthy Eating Index (AHEI) evaluates overall diet quality and its association with health outcomes. This cross-sectional study aimed to explore the relationship between diet quality, measured by the AHEI, and sleep quality in university students, while adjusting for potential confounders such as physical activity, daily energy intake, and socio-economic status.
resultsThe findings revealed no significant relationship between AHEI and sleep quality, both before and after adjusting for potential confounding variables (P = 0.781, P = 0.454). However, specific components of the AHEI, particularly fruit and polyunsaturated fatty acids (PUFAs), showed significant associations with sleep quality. Higher fruit intake was linked to better sleep quality (OR = 0.856, P = 0.013), while surprisingly, increased PUFA consumption was associated with poorer sleep quality (OR = 1.377, P = 0.007). These results suggest that while AHEI did not correlate with sleep quality, individual dietary components, particularly fruit and PUFAs, might be associated with sleep quality.
