Examining the relationship between oral health indicators, obesity, and Xerostomia in older adults.
Article in BMC public health, 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
INTRODUCTION AND
objectiveObesity is becoming a hot topic for people and governments around the world, with many countries even considering it an epidemic. A group of researchers has made new findings about the link between obesity and oral health, making the issue even more sensitive than before. According to the findings, clear signs of periodontal disease are seen in people with a body mass index (BMI) above 30. Also, xerostomia is actually a subset of oral health that can significantly affect various aspects of oral health. Saliva plays an important role in maintaining oral health by keeping your mouth moist, cleaning your teeth, and fighting bacteria. Therefore, this study aimed to explore the association between obesity indicators, general oral health variables, and xerostomia.
methodsThis cross-sectional study involved 439 adults aged 50 years or older. Data were collected using a structured questionnaire consisting of five sections: (I) demographic information, (II) oral health (issues such as loose teeth, tooth loss, use of dentures/implants, bleeding gums - self based on reported questionnaires and dental examination), (III) general health, (IV) overweight and/or obesity ( based on BMI- Height and weight measurement by a final year dental student), and (V) xerostomia (self-reported questionnaires). Statistical analysis was performed using the SPSS 24 software, with methods including T-test, Kruskal-Wallis, ANOVA, Chi-Square test, Pearson correlation coefficient, and logistic regression. A significance level of P < 0.05 was set for analyzing relationships.
resultsThe study included 312 female and 127 male participants. The average age, body mass index (BMI kg/m
conclusionThe study concludes that the prevalence of xerostomia is 39.6%, as reported by participants. Age emerged as a critical factor influencing this condition, while BMI and WHtR showed no direct relationship with xerostomia itself but were significantly related to tooth loss patterns. Notably, the highest prevalence of xerostomia was observed in patients with pulmonary disease (Asthma and respiratory allergies, COPD (Chronic Obstructive Pulmonary Disease).
