Insomnia and Incident Cardiovascular Disease in US Hispanic/Latino Adults: Results From HCHS/SOL.
Article in Journal of the American Heart Association, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundInsomnia has been recognized as an independent cardiovascular risk factor, but longitudinal evidence remains limited.
methodsWe analyzed data from 3635 participants in the HCHS/SOL (Hispanic Community Health Study/Study of Latinos). Insomnia was assessed at baseline using the Women's Health Initiative Insomnia Rating Scale and evaluated by insomnia group status, symptom severity, specific symptom dimensions, and sleep duration. The primary outcome was incident cardiovascular disease (CVD) over a median follow-up of 6.05 years, defined using Framingham composite criteria. Cox proportional hazards models were used to estimate adjusted hazard ratio (HR) and 95% CI. Subgroup and interaction analyses examined effect modification by age and sex.
resultsInsomnia was independently associated with a 78% increased risk of incident CVD (HR, 1.78 [95% CI, 1.02-3.12],
conclusionsThis study first demonstrates a prospective link between insomnia and incident CVD in a large cohort of US Hispanic/Latino adults. Baseline insomnia conferred an increased risk of developing CVD, particularly among men and younger adults. Early morning awakening drove most of this association, underscoring the need for targeted sleep interventions in this population.
