Prevalence, predictors and severity of xerostomia in adult patients in general dental care.
Article in Frontiers in oral health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
Objectives: While xerostomia (subjective dry mouth) is frequently studied in elderly populations, this study focuses on adults aged 18-82 years to explore prevalence across a broader age spectrum, including younger adults who may experience xerostomia due to medications or systemic conditions. The objective of this study was to determine the prevalence and severity of xerostomia in patients visiting general dental care, and to assess whether age, sex, comorbidities, and medications are associated with the condition. Methods: This cross-sectional study included adult patients (aged ≥ 18 years) visiting two general dental clinics in Region Västra Götaland in Sweden. Patients agreeing to participate were asked, "Have you experienced dry mouth in the last six months?". Participants replying "Yes" filled in the 11-item questionnaire Xerostomia Inventory to determine variability and severity of symptoms. Participants reporting no experience of dry mouth the last six months were included in the non-xerostomia group. Results: Out of 344 participants, the prevalence of xerostomia was 34.6% ( Conclusion and clinical relevance: The prevalence of xerostomia was high among patients seeking general dental care. Since early diagnosis and preventive dental care are crucial for managing the condition, awareness of the association between medications and xerostomia could benefit dental and health care professionals, ultimately improving patient outcomes.
