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
backgroundThe associations of early-onset coronary heart disease (CHD) and genetic susceptibility with incident dementia and brain white matter hyperintensity (WMH) remain unclear. Elucidation of this problem could promote understanding of the neurocognitive impact of early-onset CHD and provide suggestions for the prevention of dementia.
objectivesThis study aimed to investigate whether observed and genetically predicted early-onset CHD were related to subsequent dementia and WMH volume.

participants500 671 individuals without dementia at baseline. MEASUREMENTS: Early-onset CHD (male ≤55 years; female ≤65 years) was ascertained using hospital inpatient records. Incident dementia including all-cause dementia, Alzheimer's disease, and vascular dementia was ascertained using hospital inpatient records, mortality register data, and self-reported data. WMH volume was measured through brain magnetic resonance imaging (MRI). Cox proportional hazards models and linear regression models were used to analyze the associations of early-onset CHD with incident dementia and WMH. Subsequently, a polygenetic risk score (PRS) analysis was conducted to investigate the associations of genetically predicted early-onset CHD with outcomes.
resultsAmong 500 671 individuals (female: 272 669, 54.5%; mean age: 57.0 ± 8.1 years), 9 294 dementia occurred during a median follow-up of 13.8 years. Compared with the non-CHD group, both early-onset (n = 16 133) and late-onset CHD (n = 43 944) groups had higher risks of developing dementia (hazard ratio [HR]: 1.99, 95% confidence interval [CI]: 1.81 to 2.19 for early-onset group; HR: 1.20, 95% CI: 1.14 to 1.27 for late-onset group). Among CHD participants, early-onset CHD was associated with a significantly higher risk of incident dementia, compared with late-onset CHD (HR: 1.56, 95% CI: 1.39 to 1.75). In a subset of 40 290 individuals who completed brain MRI scans during a median follow-up of 9.3 years, participants with early-onset CHD exhibited the largest WMH volume among the three groups (early-onset CHD, late-onset CHD, and non-CHD, P
conclusionsEarly-onset CHD and genetic susceptibility are associated with a higher risk of incident dementia and a larger WMH volume. Additional attention should be paid to the neurocognitive status of individuals with early-onset CHD.
