Chewing ability and its associated factors in maintenance hemodialysis patients: a cross-sectional study.
Article in BMC oral health, 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
backgroundChewing difficulty is prevalent yet understudied in maintenance hemodialysis (MHD) patients, despite its critical role in overall health. This study aimed to investigate the current status of chewing ability and its associated factors in Chinese MHD patients.
methodsA cross-sectional study was conducted at a tertiary hospital in Chengdu from July to October 2024. Chewing ability was objectively assessed using color-changeable gum, with grades 1–2 defining decreased function. Other variables included general information, anxiety and depression symptoms, nutritional status, and activity of daily life (ADL). Multivariable logistic regression identified the factors influencing chewing ability.
resultsA total of 154 MHD patients aged ≥ 55 years were included in this study, and the prevalence of decreased chewing ability was 27.3%. Associated factors included: number of remaining teeth < 20 (OR = 4.66, 95%CI: 1.91–11.35), subjective chewing difficulty (OR = 3.40, 95%CI: 1.22–9.44), low articulatory oral motor skills (OR = 3.65, 95%CI: 1.47–9.10), and malnutrition (OR = 4.91, 95%CI: 1.82–13.27) (P < 0.05).
conclusionsMHD patients are more likely to have decreased chewing ability than the general population. HD staff can provide comprehensive management based on oral status examinations, self-reports of oral health outcomes, and validated nutritional screenings.
