Integrative evidence linking excessive daytime sleepiness, narcolepsy, and hypertension: insights from NHANES, Mendelian randomization, and proteomics.

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
backgroundThis study aimed to explore associations and causality between excessive daytime sleepiness (EDS), narcolepsy, and hypertension.
methodsPublicly available data from the National Health and Nutrition Examination Survey (NHANES), genome-wide association studies (GWAS), and protein quantitative trait locus (pQTL) data sets were used for analysis. Logistic regression models assessed the association between different frequencies of EDS and hypertension, and sex-stratified subgroup analyses were also performed. Bi-directional Mendelian randomization (MR) evaluated the causal effect of narcolepsy on hypertension. Proteome-wide MR and colocalization analyses were conducted to identify potential protein biomarkers and shared genetic variants.
resultsEDS with different frequencies is associated with hypertension after adjusting for the covariates (rarely: OR = 1.383, 95% CI 1.013-1.889, P = 0.041; sometimes: OR = 1.487, 95% CI 1.105-1.999, P = 0.009; often: OR = 2.041, 95% CI 1.468-2.839, P < 0.001; almost always: OR = 1.581, 95% CI 1.076-2.323, P = 0.020). Subgroup analysis suggested that this effect is significant in males. MR analysis revealed a causal association between narcolepsy and hypertension (OR = 1.038, 95% CI 1.006-1.071, P = 0.019), with no evidence of reverse causality. The protein OLFML3 was causally associated with the increased risk of both narcolepsy (OR = 2.412, 95% CI 1.070-5.436, P = 0.034) and hypertension (OR = 1.237, 95% CI 1.106-1.384, P < 0.001) in proteome-wide MR analysis.
conclusionsThis study provides integrative evidence of a causal relationship between narcolepsy and hypertension, highlighting OLFML3 as a potential biomarker for both conditions.
