A multicenter survey on the current status of chronic cough and its impact on quality of life in Guangdong, China.
Article in Journal of thoracic disease, 2022. 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
Background: Chronic cough is a troublesome clinical problem with long-term impacts at the patient level. However, the burden of chronic cough in China is largely unknown. Thus, we performed a multicenter cross-sectional survey on the current status of chronic cough and its impact on quality of life in Guangdong, south China. Methods: Using a standardized questionnaire, we extracted and analyzed the relevant data on demographics, number of visits to a doctor, previous diagnosis, previous medications used and initial diagnosis. Cough-specific quality of life was measured by the Mandarin Chinese version of the Leicester Cough Questionnaire (LCQ-MC). Results: Of 933 patients from 13 tertiary medical centers in Guangdong, 52.2% were female, the median age was 40.0 [interquartile range (IQR), 31.0-52.0] years, and the median duration of chronic cough was 6.0 (IQR, 3.0-24.0) months. Over half (n=452, 54.0%) of the patients had visited physicians ≥3 times for cough. In terms of previous diagnosis, bronchitis (n=432, 46.5%) had been most frequently diagnosed, followed by pharyngitis (n=246, 26.5%) and asthmatic cough (n=98, 10.5%). A majority of patients with chronic cough had used antitussive agents (n=539, 58.5%), antibiotics (n=374, 40.6%) and traditional Chinese medicine (TCM) (n=294, 31.9%). Among the three subscales of the LCQ-MC, we observed lower scores in the mental health domain than in the physical and social domains (both P<0.001). Additionally, lower LCQ-MC scores were found in females and patients who saw the doctor >3 times for both the total and three subscale scores (all P<0.05). Conclusions: Misdiagnosis and inappropriate treatment are prevalent in patients with chronic cough and lead to considerable antibiotic abuse. Chronic cough markedly affects suffers' quality of life, especially for women.
