Accuracy of a questionnaire on xerostomia as a screening tool for hyposalivation.
Article in International dental journal, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers, 1 of them a synthesis that pooled it.
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
objectiveDetermine the accuracy of a questionnaire on xerostomia as a screening tool for hyposalivation.
methodsA total of 402 adults awaiting dental care at a public healthcare service answered an eight-item questionnaire addressing xerostomia and were submitted to stimulated sialometry, with ≤ 0.7 mL/min considered indicative of hyposalivation. Reproducibility and internal consistency of the questionnaire were evaluated. The correlation between the score and salivary flow was investigated. The total score was also compared between groups with and without hyposalivation and diagnostic precision measures were calculated.
resultsHyposalivation was identified in 162 participants (40.3%) and a total of 229 (57.0%) answered affirmatively to at least one question. The responses to each question revealed variable reproducibility (κ = 0.450-0.785) and satisfactory internal consistency (Cronbach's α = 0.70). Individuals with a larger number of positive answers had lower salivary flow (Spearman's ρ = -0.193; P < 0.001). The mean number of positive answers was greater in the group with a clinical diagnosis of hyposalivation compared to those without low salivary flow. The sensitivity of the screening tool was 64.8%, with an area under the ROC curve of 0.60 (95% confidence interval: 0.547-0.645; P < 0.001).
conclusionThe questionnaire proved to be useful for the epidemiological screening of individuals with possible hyposalivation.
