Nutritional interventions and sleep quality in obese individuals: a systematic review and meta-analysis of randomized control trials.
Synthesis in Sleep & breathing = Schlaf & Atmung, 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
purposePoor sleep is closely associated with obesity and contributes to hormonal dysregulation and weight gain. This meta-analysis aimed to evaluate the effects of nutritional interventions on the sleep quality of individuals with obesity, focusing on strategies, such as calorie restriction, high-protein diets, and plant-based supplementation.
methodsA systematic literature search was conducted on PubMed, Embase, Web of Science, and the Cochrane Library, covering publications from inception up to January 2025. Randomized controlled trials (RCTs) assessing nutritional interventions and sleep quality were also included. The risk of bias (ROB) was assessed using Cochrane's ROB 2 tool, and a meta-analysis was performed using the Comprehensive Meta-Analysis software. The results were reported as odds ratios (ORs) with 95% confidence intervals (CIs), and heterogeneity was evaluated using the I² statistic.
resultsEleven RCTs involving 637 participants demonstrated that compared with the controls, the nutritional intervention significantly improved sleep quality (OR = 2.52, 95% CI [1.57, 4.03], P = 0.000). Specific interventions, such as saffron supplementation (OR = 11.10, P = 0.000), showed varying degrees of effectiveness. Long-term interventions (≥ 16 weeks) yielded consistent benefits, whereas moderate heterogeneity was observed (I² = 67.43%, P = 0.027).
conclusionNutritional interventions, especially those that include calorie restriction, high-protein diets, and plant-based supplementation, have the potential to improve sleep quality in adults with obesity. Long-term interventions (≥ 16 weeks) may offer the most effective benefits.
