Menopausal Age, Number of Live Births, and Risk of Atrial Fibrillation: The Cardiovascular Health Study.
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
backgroundFemale reproductive factors including menopausal age and number of live births have been associated with cardiovascular disease risk, but their role in atrial fibrillation (AF) is underexplored, especially in older adults.
methodsWe analyzed data from the CHS (Cardiovascular Health Study), a US population-based longitudinal study of adults aged ≥65 years including 3065 women reporting their menopausal age and 3236 reporting number of live births at participation. We followed participants for incident AF until June 2015. NT-proBNP (N-terminal pro-B-type natriuretic peptide) was measured at baseline. Maximal P-wave duration, P-wave terminal force in V
resultsAfter a median follow-up of 7.5 years, 1266 women (41.3%) developed AF. Each 5-year increase in menopausal age was associated with lower AF risk (hazard ratio [HR], 0.96 [95% CI, 0.92-1.00]). Menopausal age <40 years was associated with higher AF risk (HR, 1.21 [95% CI, 1.02-1.44]). No association was found between the number of live births and AF risk (HR, 0.98 [95% CI, 0.95-1.02]). Cross-sectional analyses showed younger menopausal age was associated with higher NT-proBNP levels, longer maximal P-wave duration, and longer P-wave dispersion.
conclusionsAmong women aged ≥65 years, earlier menopausal age was associated with higher NT-proBNP, longer P-wave duration, longer P-wave dispersion, and higher AF risk. Number of live births was not associated with these end points.
