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
Identifying key risk factors associated with sleep disorders is critical for enabling early intervention and risk stratification. The neutrophil-percentage-to-albumin ratio (NPAR), a readily available composite inflammatory indicator, demonstrates distinct advantages in disease risk assessment. Using nationally representative data from the National Health and Nutrition Examination Survey (NHANES), this groundbreaking study investigates for the first time the association between NPAR and prevalence of sleep disorders. This cross-section study analyzed data from NHANES. Weighted multi-variable logistic regression models were employed to examine the cross-sectional association between the NPAR and prevalence of sleep disorders. The relationship between these variables was further visualized using restricted cubic splines (RCS). Additionally, subgroup analyses and interaction tests conducted to assess effect modifications by key covariates. This study included 4574 participants, of these 1287 individuals (28.1%) were diagnosed with sleep disorders. The regression model showed a significant correlation between NPAR and the prevalence of sleep disorders (odds ratio (OR) = 1.076, 95% confidence interval (CI): 1.045-1.107, P < .001). This association remained robust under sequential adjustment: for demographic con-founders (OR = 1.058, 95% CI: 1.029-1.087, P < .01), and additional adjustment for socioeconomic factors (OR = 1.051, 95% CI: 1.019-1.083, P = .049). The RCS analysis further confirmed this positive correlation (p overall < 0.001). Subgroup analyses confirmed consistent associations across different demographic groups, and the association was not significantly influenced by factors other than gender. This study found a robust association between NPAR and sleep disorders, suggesting that higher NPAR levels are associated with an increased likelihood of developing sleep disorders.
