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
Introduction: Influenza is a significant cause of morbidity among patients with asthma and chronic obstructive pulmonary disease (COPD). In Malaysia, the Ministry of Health recently updated the national formulary to include influenza vaccination for senior citizens aged 60 years and above with at least one chronic illness, effective from 18 February 2025. However, the uptake rate of influenza vaccination among patients with asthma and COPD remains unclear. This study aimed to determine the association between sociodemographic factors, health belief model components and influenza vaccine uptake among patients with asthma or COPD in Klang Valley. Methods: A cross-sectional survey was conducted among 200 adults with asthma or COPD attending follow-up at five primary care clinics in Klang Valley. Sociodemographic data, vaccination history and vaccination beliefs were recorded using a questionnaire based on the health belief model. Data were examined using univariate and multivariate analyses. Results: A total of 200 patients participated. The influenza vaccine uptake rate was 24.0%. The employed patients were significantly more likely to be vaccinated (odds ratio [OR] =3.68; 95% confidence interval [CI] = 1.09-12.38; P=0.036). Stronger cues to action increased uptake (OR = 4.04; 95% CI = 1.94-8.40; P = 0.001), with healthcare provider recommendation being the main contributing factor. Higher perceived barriers reduced uptake (OR = 0.41; 95% CI = 0.18-0.93; P = 0.032), particularly concerns regarding vaccine side effects. Conclusion: Influenza vaccine uptake among high-risk patients in Malaysia is low. Employment, healthcare provider recommendations and perceived barriers strongly influence vaccination behaviour.
