Cardiovascular Events in US Adults Aged ≥80 Years: Incidence, Risk Factors, and Outcomes.
Article in Circulation. Population health and outcomes, 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
backgroundEstimating risk and risk factors for cardiovascular disease (CVD) events and mortality following CVD events can inform strategies for lowering risk in older adults.
methodsWe estimated risk factors for the 5-year cumulative incidence of CVD events including nonfatal myocardial infarction, fatal coronary heart disease, stroke, and heart failure among adults aged <70, 70 to <80, and ≥80 years in the Reasons for Geographic and Racial Differences in Stroke (REGARDS) study. The REGARDS study is a prospective cohort study with enrollment across the contiguous United States and adjudicated CVD events. Data on CVD risk factors were collected during a study interview and in-home study visit from 2013 to 2016. In addition, we estimated 1-year mortality after the first CVD event during follow-up.
resultsAmong 4621, 4938, and 2450 participants aged <70, 70 to <80, and ≥80 years, the 5-year cumulative incidence of CVD events was 5.3% (95% CI, 4.7%-6.0%), 10.7% (95% CI, 9.9%-11.6%), and 17.2% (95% CI, 15.8%-18.8%), respectively. Diabetes and hypertension were associated with CVD events among participants aged <70 years (hazard ratio [HR], 1.42 [95% CI, 1.00-2.03] and 1.58 [95% CI, 1.19-2.09], respectively) and 70 to <80 years (HR, 1.41 [95% CI, 1.09-1.83] and 1.73 [95% CI, 1.43-2.08], respectively) but not among those aged ≥80 years (HR, 1.03 [95% CI, 0.81-1.32] and 1.07 [95% CI, 0.84-1.35], respectively). Among those aged ≥80 years, risk factors for CVD events included LDL-C (low-density lipoprotein-cholesterol) ≥100 mg/dL (HR, 1.24 [95% CI, 1.01-1.51]), hsCRP (high-sensitivity C-reactive protein) ≥3 mg/L (HR, 1.27 [95% CI, 1.03-1.55]), albuminuria (HR, 1.61 [95% CI, 1.30-1.98]), and a prior history of CVD (HR, 2.25 [95% CI, 1.84-2.76]). Among participants aged ≥80 years, the 1-year cumulative incidence of all-cause mortality following a CVD event was 53.1% (95% CI, 48.3%-57.8%) versus 5.7% (95% CI, 3.5%-7.9%) in age-matched participants who did not have a CVD event.
conclusionsThe risk for CVD events in adults aged ≥80 years was high, and the association was stronger for albuminuria and inflammation versus hypertension and diabetes.
