Characterizing adult asthma: a cross-sectional epidemiologic study from the canadian primary care sentinel surveillance network.
Article in NPJ primary care respiratory medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
National asthma prevalence data in Canada typically come from health surveys or administrative records. Since most asthma care is provided by family physicians, primary care electronic medical records (EMRs) may offer valuable insights into asthma epidemiology and treatment patterns. This study aimed to estimate the prevalence of adult asthma across Canada using national EMR data, examine the demographics and comorbidities of asthma patients, and review national prescribing practices. We used a validated EMR case definition for adult asthma applied to the Canadian Primary Care Sentinel Surveillance Network (CPCSSN) database, which includes data from 12 networks across Canada. We identified patients with at least one encounter in a two-year period and estimated asthma prevalence, stratified by age, sex, and BMI. Comorbidity rates and medication prescriptions were assessed in patients with asthma. Among 854,567 adults, 94,410 were identified with confirmed/suspected asthma (11% prevalence). Asthma was more common in females (12 vs. 10%, p < 0.0001), across all age brackets except 18-29 years old. A chi-square test for trend showed a decrease in prevalence with increasing age (p < 0.0001). Females with asthma had a higher prevalence of ≥4 comorbidities than males (33 vs. 30%, p < 0.0001). Additionally, 13% of asthma patients were prescribed only as-needed short-acting bronchodilators, without a controller. The 11% asthma prevalence found in this study aligns with national survey estimates, providing support for the use of EMRs in disease and practice surveillance. Future efforts should focus on integrating tools within EMR to support asthma diagnosis and treatment adherence.
