Association Between EAT-Lancet Diet Adherence and Sleep Quality in Lactating Women: A Cross-Sectional Analysis.
Article in Health science reports, 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
Background and Aims: In recent years, the sustainable EAT-Lancet diet (ELD) has garnered attention for its health benefits, especially regarding mental health and cognitive function. However, its impact on sleep health remains underexplored. This study aims to investigate the relationship between ELD and sleep quality, focusing on lactating women, a demographic particularly susceptible to sleep disturbances. Methods: The study involved 350 lactating women aged 20-35, randomly selected from health clinics. Dietary intake was assessed using a Food Frequency Questionnaire (FFQ). ELD was evaluated using an index developed by Kesse-Guyot, while sleep quality was measured through the self-reported Pittsburgh Sleep Quality Index (PSQI). Results: Each one-unit increase in ELD score was associated with 0.9% lower odds of being in a higher PSQI category in the crude model (OR = 0.991; 95% CI: 0.985-0.997; Conclusion: This study is the first to show a statistically significant association between ELD adherence and sleep quality in lactating women. The effect size is modest, suggesting only slight improvements in sleep. As this is a cross-sectional study, causality cannot be inferred, and further research is needed.
