Typical antipsychotics is associated with increased risk of severe exacerbation in asthma patients: a nationwide population-based cohort study.
Article in BMC pulmonary medicine, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundSevere asthma exacerbation reduces patients' quality of life, results in visits to the emergency department (ED) and hospitalization, and incurs additional medical costs. Antipsychotics block receptors with bronchodilation function; however, the association between antipsychotic use and severe asthma exacerbation is unknown. This study aimed to investigate the effects of antipsychotics on asthma-related ED visits and hospitalizations.
methodsA case-crossover design was used in this study. Using the 2003-2017 Taiwan National Health Insurance Reimbursement Database, we established a cohort of 18,657 adults with asthma exacerbation leading to ED visits or hospitalization. Univariate and multivariate conditional logistic regressions were conducted to explore the association between antipsychotic use and severe asthma exacerbation. Subgroup analyses of different classes, doses, receptor functions of antipsychotics, different psychiatric disease, and sensitivity analyses of excluding patients with schizophrenia were also performed.
resultsAntipsychotic use was associated with a higher risk of severe asthma exacerbation (adjusted odds ratio [OR]: 1.27; 95% confidence interval [CI] 1.05-1.54; P = 0.013) compared with no use of antipsychotics. The use of typical antipsychotics increased the risk of severe asthma exacerbation (adjusted OR: 1.40, 95% CI 1.10-1.79, P = 0.007), whereas the use of atypical antipsychotics did not. These results did not change after the exclusion of patients with schizophrenia. There was a dose-dependent effect of antipsychotics (trend test, P = 0.025). Antipsychotics that block the M2 muscarinic or D2 dopaminergic receptors were associated with an increased risk of severe asthma exacerbation (adjusted OR: 1.39, 95% CI 1.10-1.76, P = 0.007 and adjusted OR: 1.33, 95% CI 1.08-1.63, P = 0.008, respectively). However, use of antipsychotics did not increase risk of severe asthma exacerbation in patients with psychiatric disorder.
conclusionsThe use of typical antipsychotics is associated with a dose-dependent increased risk of severe asthma exacerbation, especially for patients without psychiatric disorders. Further research on the impact of typical antipsychotics on asthma exacerbation is warranted.
