Combined Influence of Dental Caries and Periodontal Disease on Ischemic Stroke Risk.

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
Background and Objectives: Periodontal disease (PD) and dental caries are prevalent chronic oral inflammatory conditions associated with systemic health outcomes. Individually, both have been linked to an increased risk of ischemic stroke, a leading cause of morbidity and mortality. However, few studies have examined the combined effect of PD and dental caries on stroke, stroke subtypes, and major adverse cardiovascular events (MACEs) within US cohorts. We aimed to evaluate the individual and joint associations of PD and dental caries with incident ischemic stroke, stroke subtypes, and MACEs and assess the relationship between regular dental care utilization and oral disease status. Methods: We analyzed data from participants in the Atherosclerosis Risk in Communities study who completed dental assessments during Visit 4 (1996-1998). Participants with previous ischemic stroke, coronary heart disease (CHD), or dental caries without PD were excluded. Oral health status was categorized as good oral health, PD only, or PD with(+) caries. Incident ischemic stroke and MACEs (ischemic stroke, myocardial infarction, or fatal CHD) were identified using adjudicated records through 2019. Cox proportional hazard models estimated hazard ratios (HRs) for outcomes, adjusting for demographics and vascular risk factors. The association of regular dental care with oral disease status was analyzed using logistic regression. Results: Among 5,986 participants (mean age 63 ± 5.6 years; 52% female), 1,640 had good oral health, 3,151 had PD only, and 1,195 had PD + caries. The incidence of ischemic stroke was 4.1%, 6.9%, and 10.0% across groups, respectively. In fully adjusted models, PD + caries was associated with increased risk of ischemic stroke (HR 1.86; 95% CI 1.32-2.61) and MACEs (HR 1.36; 95% CI 1.10-1.69). Elevated risk was observed for thrombotic (HR 2.27; 95% CI 1.22-4.24) and cardioembolic (HR 2.58; 95% CI 1.27-5.26) strokes. Regular dental care was associated with lower odds of PD (odds ratio [OR] 0.71; 95% CI 0.58-0.86) and PD + caries (OR 0.19; 95% CI 0.15-0.25). Discussion: Co-occurring PD and dental caries were independently associated with increased risk of ischemic stroke and MACEs. Regular dental care may reduce this risk by improving oral health. Limitations include reliance on one-time dental assessment and residual confounding.
