Does periodontitis have any association with mild cognitive impairment?
Article in Evidence-based dentistry, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
data sourcesThis study aimed at determining the association between periodontitis and mild cognitive impairment. For this, different electronic databases, including PubMed, Scopus, Embase and Web of Science, were searched for finding the relevant literature. In addition, hand searching of relevant journals was also done to find gray literature. STUDY SELECTION: The systematic review included observational studies only. Accordingly, case-control, cohort and cross-sectional studies were searched. The search strategy was based on PECO framework, wherein the studies which included patients with/without periodontitis and patients with/without mild cognitive impairment (MCI) were included. DATA EXTRACTION AND SYNTHESIS: A total of 7 studies were included and the data from these studies and the data including bibliographic details, demographic data, data about periodontitis, presence of MCI etc. was extracted from the included articles. The extracted data, was then assessed for heterogeneity using clinical parameters and I
resultsMeta-analysis was done to determine the association between periodontitis and MCI and significantly higher incidence of MCI was found in patients with periodontitis OR = OR, 1.70 (95% CI: 1.24-2.32, p < 0.001). A subgroup analysis was done by including the studies comparing incidence of MCI in patients with severe periodontitis, which resulted in even stronger association with an OR of 2.09 (95% CI: 1.49-2.92, p < 0.001). Lastly, periodontal parameters, including CAL, PPD, and PI were compared amongst patients with/without MCI. Significant differences were observed for both CAL and PI, with worsening of values in patients with MCI. Observed mean difference for CAL and PI were 0.44 (95% CI: 0.12-0.75) and 0.72 (95% CI:0.50-0.93), respectively. NS differences were observed for PPD values with a mean difference of 0.21 and 95% CI as -0.08 to 0.49.
conclusionsStrong association between periodontitis and MCI was observed, indicating periodontitis to be a risk factor for MCI.
