Triggered chain reaction: The meanings of symptom clusters for patients with chronic obstructive pulmonary disease: A cross-sectional qualitative study.
Article in PloS one, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeSymptoms in chronic obstructive pulmonary disease (COPD) commonly co-occur as 'symptom clusters', yet little is known about how patients interpret and make sense of these experiences. This study aimed to explore the meanings patients with COPD attribute to symptom clusters, their impact on health-related quality of life, and the strategies used to manage them.
methodsA qualitative study using semi-structured interviews was conducted with a purposive sample of 30 patients with COPD recruited from a university teaching hospital in China. Data were analysed using the Framework approach, informed by the Theory of Unpleasant Symptoms and the concept of biographical disruption.
resultsThree interrelated themes were identified. First, participants understood symptom clusters as dynamic, interacting experiences, often organised around "trigger symptoms" (e.g., cough precipitating breathlessness and fatigue), rather than as isolated symptoms. Second, these clusters disrupted multiple dimensions of everyday life, including physical functioning, social participation, and sense of self. Third, participants actively negotiated symptom burden through a range of adaptive strategies, prioritising symptoms based on their perceived meaning and impact rather than clinical severity. These findings highlight how symptom experiences are shaped by both physiological interconnections and personal interpretations.
conclusionsThis study provides novel insight into how people with COPD experience symptom clusters as interconnected, meaning-laden phenomena. Recognising the role of "trigger symptoms" and patients' subjective prioritisation of symptoms has important implications for person-centred assessment and supports the development of targeted, mechanism-informed approaches to symptom management in COPD. I can't walk long distances. I can't go out and spend time with my friends. This is a big problem in my life. (69-year-old male, GOLD stage III) Other people can run around. They visit relatives or friends during the holidays. I can't. I cough all day long and can only stay at home. (63-year-old female, GOLD stage IV).
