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
Dietary health and sleep disorders are significant global public health concerns. This study aims to explore the potential relationship between the dietary inflammatory index (DII) and sleep disorders, providing insights into how dietary factors may influence sleep quality. We utilized epidemiological data from 24,870 participants in the National Health and Nutrition Examination Survey from 2007 to 2018, employing logistic regression and restricted cubic spline (RCS) analysis to assess the relationship between DII and sleep disorders. Additionally, Mendelian randomization (MR) analysis was conducted to investigate the causal relationships of individual DII components with sleep disorders. Our MR analysis revealed that genetically determined selenium has a protective effect against sleep apnea (odds ratio [OR] = 0.92, 95% confidence intervals [CI] 0.86-0.98, P = .007), while genetically determined vitamin C and monounsaturated fatty acids also demonstrated protective effects against sleep-wake disorders (OR = 0.57, 95% CI 0.33-0.97, P = .039; OR = 0.08, 95% CI 0.01-0.74, P = .026). These findings support the potential role of an anti-inflammatory diet in improving sleep health. Our results also showed that multivariable logistic regression revealed that for each unit increase in DII, the risk of sleep disorders increased by 12.9% (P < .001). After adjusting for age, sex, race, education, household income, hypertension, and diabetes, the risk still increased by 11.2%. Restricted cubic spline analysis indicated a significant nonlinear relationship between DII and sleep disorders. Our study suggests that a higher DII significantly increases the risk of sleep disorders. An anti-inflammatory diet may provide a protective effect, highlighting the importance of dietary adjustments in preventive strategies for sleep-related health issues.
