Oral Health Related Factors Predicting Severe COVID-19 Disease in Elderly Swedes.
Article in Journal of oral rehabilitation, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectivesTo analyse different background factors that may serve as predictors for acquiring symptoms of severe COVID-19 disease.
methodsA postal questionnaire was sent to the total population of individuals born between 1942 (80 years, n = 6299) and 1932 (90 years, n = 1904) living in the Örebro and Östergötland counties, Sweden, in 2017 and repeated in 2022. Tentative predictive factors for self-reported severe COVID-19 disease were based on the responses from the 2017 questionnaire related to general and oral health and prior to the outbreak of the COVID-19 pandemic.
resultsResponse rate to the main questionnaire in 2022 was 66% (5375/8203), and 577 reported having been sick with COVID-19 out of which 359 agreed to answer a separate questionnaire on COVID-19. This questionnaire was returned by 278/359 of the participants corresponding to a response rate of 77%. Information gleaned from the 2017 pre-COVID-19 survey revealed a relatively large number of associations between severity of subsequently self-reported COVID-19 disease and several diverse tentative related factors found in unadjusted regression analyses. Based on statistically significant correlations in the adjusted regression analysis, significant predictive factors (based on self-reports from 2017) for contracting severe COVID-19 were in decreasing order of odds ratios (OR): reported removable partial or complete denture usage (OR 6.2, CI 2.2-17.2); reported periodontal problems in the past year (OR 3.4, CI 1.1-10.4); and reported daytime dry mouth (OR 2.5, CI 1.2-5.2).
conclusionRemovable dentures, periodontal problems and daytime dry mouth were predictors for developing symptoms of severe COVID-19 disease.
