A meta-analysis of the association between the presence of Helicobacter pylori and periodontal diseases.

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 objective of this meta-analysis is to evaluate the association between the presence of Helicobacter pylori (H pylori) and periodontal disease (PD).
methodsPubMed and EMBASE databases were searched to identify eligible articles published from inception up to April 2018. Further articles were retrieved through a manual search of recent reviews. Cross-sectional studies, case-control studies and cohort studies reporting the association between H pylori and PD were included. The pooled odds ratio (OR) and their 95% confidence interval (CI) were calculated.
resultsFour case-control studies and nine cross-sectional studies were included. A total of 6800 patients were included in this review. The odds for oral H pylori positivity was 2.31 times (95% CI: 1.99-2.68) greater than those without H pylori. Subgroup analyses involving different study locations, designs, and types of study population showed the similar results. The pooled OR for the gastric disease patients was the largest (3.50, 95% CI: 2.22-5.53, five articles). Stomach H pylori was also significantly associated with PD, with OR 2.90 (95% CI: 1.37-6.14, two articles).
conclusionsThis meta-analysis supports an association between H pylori and PD. More well-designed studies, especially prospective cohort studies are necessary to confirm these results.
