Parkinson's Disease and Salivary Issues: A Survey.
Article in Gerodontology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundSalivary dysfunction, including xerostomia and drooling, is common in Parkinson's disease and further impairs oral health and quality of life, which are already compromised in this population. Their effective management demands deeper insight into the complexity of salivary dysfunction.
objectiveTo examine the occurrence and associations of xerostomia and drooling complaints in individuals with Parkinson's disease.
methods111 individuals with Parkinson's disease (69.9 ± 7.7 years; 46.8% female) participated in an online survey. The questionnaire used validated scales (e.g., Xerostomia Inventory) and original questions. After descriptive analyses, multiple linear regression analyses identified factors (e.g., severity of motor impairment) associated with severity of xerostomia and drooling.
resultsXerostomia (64.9%) and drooling (27.0%) were common, with 18.0% of the individuals experiencing both concurrently. Xerostomia was associated with the presence of jaw symptoms (B = 4.63; 95% CI 1.86-7.40), chewing gum usage (B = 1.27; 95% CI 0.52-2.02), swallowing difficulties (B = 0.41; 95% CI 0.04-0.78) and taste alterations (B = 0.15; 95% CI 0.00-0.30). Drooling was associated with the severity of motor impairment (B = 0.40; 95% CI 0.18-0.60) and with swallowing difficulties (B = 0.64; 95% CI 0.14-1.15).
conclusionsXerostomia and drooling complaints frequently co-occur in individuals with Parkinson's disease. To prevent further deterioration of the oral health-related quality of life, a comprehensive evaluation of the underlying aetiology of salivary issues in people with Parkinson's disease is crucial to assist in determining suitable treatment.
