Role of toxic and essential elements in sleep duration of patients with cardiovascular diseases.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Sleep disorders are a common aspect of cardiovascular diseases (CVDs) that can negatively impact a patient's quality of life, trigger coronary events, accelerate disease progression, and influence patient survival. This study aimed to investigate the relationship between essential and toxic elements with sleep duration among CVD patients. The study utilized cross-sectional data from 150 patients with CVDs (n = 150) from the Ravansar Non-Communicable Disease (RaNCD) Cohort Study. Serum concentrations of zinc (Zn), copper (Cu), Iron (Fe), arsenic (As), mercury (Hg), and nickel (Ni) were measured using a gas chromatography-mass spectrometry. The prevalence of short-sleep duration (< 7 h), normal sleep duration (7-8 h), and long-sleep duration (> 8 h) were 36%, 10.6%, and 53.3%, respectively. No significant differences were found among the three sleep duration categories in terms of serum concentrations of toxic and essential elements. The adjusted regression model showed that ORs for sleep duration across Zn quartiles Q1, Q2, Q3, and Q4 were 1.00 (reference), 0.32 (95% CI, 0.11-0.84), 0.31 (97.1% CI 0.11-0.81), and 0.33 (98.7% CI 0.12-0.88), respectively (p for trend = 0.006). Our findings suggest a significant relationship between serum zinc levels and sleep duration, with higher zinc concentrations being associated with optimal sleep duration.
