Chewing function and related parameters as a function of the degree of dementia: Is there a link between the brain and the mouth?
Article in Journal of oral rehabilitation, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 18 papers.
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
backgroundTo date, no study has investigated the association between chewing function and related parameters as a function of the degree of dementia using a finer subdivision of the values of the Mini-Mental State Examination (MMSE).
objectiveThis study aimed to investigate the differences in chewing function and related parameters as a function of the degree of dementia.
methodsAn analysis of cross-sectional data obtained from the OrBiD (Oral Health, Bite Force, and Dementia) pilot study was performed. The participants were stratified into five groups based on the outcomes of the MMSE (no dementia, MMSE 28-30; mild cognitive impairment, MMSE 25-27; mild dementia, MMSE 18-24; moderate dementia, MMSE 10-17; severe dementia, MMSE <10). The chewing efficiency, maximum occlusal force and related parameters (number of supporting zones, number of teeth, Eichner index, tooth/denture status, denture quality, and dental treatment needs) were recorded.
resultsThe MMSE groups showed significantly different chewing efficiencies (p = .003, Jonckheere-Terpstra test) and maximum occlusal forces (p = .003, Jonckheere-Terpstra test), but the number of supporting zones (p = .055, chi-square test) and the number of natural teeth (p = .126, chi-square test) were not different. The Eichner index, tooth/denture status, denture quality and dental treatment need showed no significant associations with the degree of dementia.
conclusionAn improvement in the usability of the measurement methods for assessing chewing function in people with dementia is needed. Research involving people with dementia is necessary because the nutritional situation often deteriorates rapidly within a multifactorial system, which includes chewing ability and oral health.
