Dietary cholesterol intake and egg consumption in relation to all-cause and cardiovascular mortality after stroke.
Article in Scientific reports, 2025. 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
The findings on the associations of dietary cholesterol intake and egg consumption with mortality in the general population remain inconclusive. Our objective was to evaluate all-cause and cardiovascular mortality in relation to dietary cholesterol intake and egg consumption in a cohort of stroke survivors, a particularly vulnerable population. We conducted a prospective cohort analysis of 1367 stroke survivors recruited across the United States between 1999 and 2018. Dietary information was evaluated by a 24-h dietary recall at baseline obtained from NHANES while mortality data were derived from the National Death Index with follow-up through 2019. To investigate the associations of dietary cholesterol intake or egg consumption with all-cause and cardiovascular mortality, Cox proportional hazards and restricted cubic splines models were utilized. After a median follow-up of 79.0 months, the incidence per 1000 person-years was 59.9 (95% confidence interval [CI], 55.2-64.9) for all-cause and 23.3 (95% CI, 20.4-26.5) for cardiovascular mortality. Each 100 mg/1000 kcal/day elevation in cholesterol intake was related to raised risk of all-cause (hazard ratio [HR], 1.16; 95% CI, 1.05-1.27) and cardiovascular mortality (HR, 1.15; 95% CI, 1.00-1.31). A greater risk of all-cause mortality was shown in participants consuming > 1 egg/day (HR, 1.40; 95% CI, 1.06-1.84). The dose-response analysis highlighted the lowest risk of all-cause mortality when egg consumption was around 33.3 g/day. The observed correlations of dietary cholesterol intake or egg consumption with all-cause and cardiovascular mortality were stronger in the subgroups with cardiometabolic diseases (obesity, hypertension, diabetes mellitus, hyperlipidemia) or risk factors for cardiometabolic diseases (advanced age). Among stoke survivors, greater dietary cholesterol connects to an escalated risk of all-cause and cardiovascular mortality in a linear manner. Moderate egg consumption (≤ 1 egg/day) is relatively safe and excessive consumption links to an elevated risk of all-cause mortality.
