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

objectivesThis study aimed to evaluate the association between the frequency of dental scaling and the risk of stroke among individuals with moderate-to-severe periodontal diseases and verify the effect of regular dental scaling on stroke risk in this population.

methodsIn this retrospective study, 25,758 subjects with moderate-to-severe periodontal diseases were selected from the Korean National Health Insurance Service-National Health Screening Cohort database. Based on the frequency of dental scaling, the subjects were divided into three groups: regular, occasional, and infrequent. Restricted cubic splines were used to evaluate hazard ratios (HRs) with 95% confidence intervals (CIs) for stroke. Additionally, landmark analysis was conducted to strengthen the reliability of the results.

resultsThere were 293, 111, and 38 stroke cases in the infrequent, occasional, and regular group, respectively. The adjusted HR for stroke in the regular group, compared to that in the infrequent group, was 0.40 (95% CI, 0.29 to 0.57). In the landmark analysis with follow-up after 1 year and after 2 years, the adjusted HR in the regular group compared to that in the infrequent group was 0.41 (95% CI, 0.28 to 0.60) and 0.50 (95% CI, 0.33 to 0.76), respectively.

conclusionsRegular dental scaling was significantly associated with a reduced risk of stroke in patients with moderate-to-severe periodontal diseases. These findings may suggest a potential preventive role of dental scaling beyond oral health. Further studies are needed to explore the underlying biological mechanisms linking periodontal care to stroke prevention and to explore causal relationships between dental scaling and stroke risk.
