Observational study in BMC oral health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03144973 (Meaning of Periodontitis in Post-operative Complications After Upper Gastrointestinal Tract Surgery), which is not on this map. Not yet cited in PubMed.

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.

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.

Abstract

backgroundPeriodontitis, a progressive inflammatory disease of the tooth-supporting structures, has direct adverse effects on systemic health. Links between periodontitis and gastrointestinal tract malignancies have also emerged in numerous studies. The aim of our study was to uncover the prevalence of periodontitis and its effects on postoperative complications among patients undergoing gastric surgery.

methodsThis prospective study took place between May 2017 and June 2019 at the Helsinki University Hospital, with data from patients undergoing gastric surgery. We recorded complications based on the Clavien-Dindo classification, and for periodontitis screening we used the aMMP-8 point-of-care test.

resultsOur study included 59 patients, of whom 29 (49%) tested positive for periodontitis. Malignant tumour histology was present in 75% of cases. Periodontitis showed no association with postoperative complications (p = 0.879): neither with surgical site infections (p = 0.149) nor with thrombotic events (p = 0.513).

conclusionsThe prevalence of periodontitis among patients undergoing gastric surgery matched that of the general population in Finland. Periodontitis did not associate with postoperative complications in surgical patients.
