Handheld Cough Testing: A Novel Tool for Cough Assessment and Dysphagia Screening.
Article in Dysphagia, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 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
Aspiration pneumonia is a leading cause of death in Parkinson's disease (PD), occurring as a result of impaired cough and swallowing function. However, portable diagnostic tools for cough assessment and dysphagia screening are limited. Therefore, the aims of this study were to determine if: (1) 'Handheld Cough Testing' (HCT), a novel tool developed for cough assessments, could detect differences in cough airflow and sensation during reflex and voluntary cough tasks; and (2) HCT could screen for dysphagia in PD with high sensitivity. Twenty-two people with PD underwent HCT and swallowing assessments. Cough airflow ('PEFR') and sensation ('UTC') was recorded during reflex and voluntary cough tasks. Flexible endoscopy was used to identify people with and without dysphagia. Within-subject statistical analyses were used to detect differences in PEFR and UTC across cough tasks and between-subject statistical analyses were used to detect differences in cough function between people with and without dysphagia. Results revealed significant differences in PEFR (p < 0.0005) and UTC (p < 0.0005) across cough tasks using HCT. Additionally, reflex cough PEFR was significantly different between people with and without dysphagia (p < 0.05). A cut-off of 42.5 L/min exhibited an excellent ability to predict dysphagia in people with PD (90.9% sensitivity; 80.0% specificity). This study revealed that HCT was a valid tool for cough assessment and dysphagia screening. It identified differences in cough airflow and sensation during reflex and voluntary cough tasks and screened for people with dysphagia in PD with high sensitivity.
