Influence of masticatory function on food preferences and cognitive performance in centenarians: an observational study.
Article in BDJ open, 2025. 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
introductionDemographic projections forecast that centenarians' population growth will continue. "CaT: Centenari a Trieste" is an ongoing study featuring the collection of demographic and anamnestic data, including the analysis of oral variables.
aimsevaluate of the possible influence of past food preferences, taste perception and masticatory function on current cognitive status in a cohort of centenarians.
designObservational transversal study. MATERIALS AND
methods31 participants with mean age 102 ± 2 performed an examination of the oral cavity including the measurement of DMFT (Decayed Missing Filled Teeth), FTUs (functional teeth units), FOUs (functional occlusal units) and 6-n-propylthiouracil (PROP) taste perception assay. Results were correlated with dementia, subjective perception of oral health and food preferences.
resultsMasticatory function did not correlate with dementia but had a significant impact on oral health perception. When analyzing variables affecting food preferences, PROP taste perception profile and DMFT resulted significantly correlated. Early edentulism didn't show to affect past dietary preferences.
conclusionsour data suggest that in centenarians masticatory function doesn't seem to correlate to cognitive function, but influences the self-perception of oral health. Such results are an interesting addition to knowledge on the topic as they refer to a population which has never been considered before.
