The Impact of Psychological Factors on Periodontitis in the Elderly: A Systematic Review.

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
Psychological factors and periodontitis are prevalent in geriatric populations, with evolving evidence suggesting potential associations. This systematic review comprehensively examines and evaluates the bidirectional relationship between psychological factors and periodontitis in older adults. Following PRISMA guidelines, systematic searches were conducted across PubMed, Google Scholar, Scopus, Embase, and Web of Science databases. The research question was structured using the PECO framework (P = older adults aged ≥ 60 years; E = presence of psychological factors; C = absence of psychological factors; O = periodontitis and its severity). Articles were selected based on predetermined inclusion/exclusion criteria, followed by data extraction. The Newcastle-Ottawa Scale assessed risk of bias and methodological quality, while the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) framework determined evidence certainty. Of 475 studies identified, 13 met the inclusion criteria for qualitative synthesis (8 on depression, 3 on stress, 1 on cognitive impairment, and 1 on examining multiple factors). For depression-periodontitis associations, results were inconsistent: four studies demonstrated positive associations, three found no significant relationship, and one had unclear findings. All three studies investigating stress-periodontitis relationships showed positive associations, suggesting a more consistent connection. The single study on cognitive impairment found significant independent associations with periodontitis after controlling for confounders. Only one longitudinal study (
