1 · What the graph read from it

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.

2 · The registry

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

aimThe study 'Periodontitis and Its Relation to Coronary Artery Disease' (PAROKRANK) reported an association between periodontitis (PD) and the first myocardial infarction (MI). This follow-up study aims to test the hypothesis that those with PD-compared to periodontally healthy individuals-are at increased risk for cardiovascular (CV) events and death.

methodsA total of 1587 participants (age <75 years; females 19%) had a dental examination including panoramic radiographs between 2010 and 2014. PD was categorized as healthy (≥80% alveolar bone height), mild/moderate (79%-66%) or severe (<66%). A composite CV event (first of all-cause death, non-fatal MI or stroke and hospitalization following to heart failure) was investigated during a mean follow-up period of 9.9 years (range 0.2-12.5 years). Participants were divided into two groups: those with and without PD. The primary event rate, stratified by periodontal status at baseline, was calculated using the Kaplan-Meier method and Cox regression.

resultsThe number of events was 187 in the 985 periodontally healthy participants (19%) and 174 in the 602 participants with PD (29%; p < 0.0001). Those with PD had a higher likelihood for a future event (hazard ratio [HR] = 1.26; 95% CI: 1.01-1.57; p = 0.038), following adjustment for age, smoking and diabetes.

conclusionThe PAROKRANK follow-up revealed that CV events were more common among participants with PD, which supports the assumption that there might be a direct relation between PD and CV disease.
