Cough related to swallowing in asthma patients.
Article in Asia Pacific allergy, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundOccurrence of cough during swallowing is common among asthma patients, but has not been investigated in detail.
objectiveWe conducted an observational study to determine the prevalence of swallowing-related cough (SRC) and its characteristics in asthma patients.
methodsAsthma patients attending our outpatient department between May 2005 and April 2007 were interviewed to investigate if they had ever experienced SRC, as well as postnasal drip or heartburn and cough related to these conditions.
resultsAmong 417 patients who completed the questionnaire, 121 patients (29.0%) had experienced SRC. Spicy and sour foods were the most frequent tussigenic foods, causing cough in 76.0% and 53.7% of the 121 patients, respectively. In patients without SRC, the prevalence rates of postnasal drip and postnasal drip-induced cough were 35.8% (106 of 296) and 7.8% (23 of 296), respectively. The corresponding prevalence rates in patients with SRC were 50.4% (61 of 121) and 37.2% (45 of 121), which were both significantly higher than in patients without cough (
conclusionSRC was frequent in asthma patients, and was closely related to postnasal drip and heartburn. Irritable larynx is one of the possible underlying mechanisms of SRC. This study was registered with the University Hospital Medical Information Network clinical trials registry (registration number: UMIN000017426).
