Knowledge, practices, and diagnostic barriers in chronic cough management among primary care doctors in Klang Valley, Malaysia: a cross-sectional survey.
Article in BMC pulmonary medicine, 2025. 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
backgroundChronic cough (CC), defined as a cough persisting for over eight weeks, presents diagnostic and management challenges in primary care, particularly in tuberculosis (TB)-endemic countries like Malaysia. This study aimed to assess the knowledge, practices and diagnostic barriers of primary care doctors in Klang Valley regarding CC.
methodsA cross-sectional online survey was conducted from October to December 2024 involving 170 primary care physicians from public and private clinics. The questionnaire covered sociodemographic, diagnostic tools, clinical strategies, perceived barriers, and training needs. Descriptive and inferential statistics, including regression analysis, were used to identify patterns and associations.
findingsOnly 18·8% of participants correctly defined CC as lasting more than 8 weeks. Most emphasized environmental and occupational history-taking but underutilized spirometry (available to only 33·5% of clinics). While chest radiography was widely available (61·2%), high patient load was significantly associated with reduced medical history-taking and chest X-ray ordering (p = 0·011). Empirical treatments, including antihistamines and bronchodilators, were commonly used. Barriers included limited diagnostic tools (53·7%), unclear referral pathways (12·8%), lack of standardized guidelines (8·7%), and time constraints (16·8%).
interpretationPrimary care doctors in Malaysia face significant limitations in CC management, particularly in defining, diagnosing, and accessing diagnostic tools. There is an urgent need for national guidelines tailored to primary care, broader access to spirometry, and structured training. Addressing these issues can improve diagnostic accuracy and reduce unnecessary investigations and treatment delays in chronic cough care.
