Clinical characteristics of adult asthma patients hospitalized by COVID-19 in Mexico City: a real-world study.
Observational study in Annals of medicine, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundThe COVID-19 pandemic raised concerns about whether individuals with chronic respiratory diseases, such as asthma, were at higher risk of severe outcomes. Although several studies were published on this topic, not all included asthma as a risk factor. Therefore, describing the clinical characteristics of COVID-19-infected asthma patients in a specialized respiratory center is valuable as a real-life study.
objectiveTo investigate the clinical characteristics and disease severity in SARS-CoV-2-infected adults with pre-existing asthma hospitalized at the National Institute of Respiratory Diseases (INER) in Mexico City.
methodsWe conducted a retrospective, observational study on adults with confirmed COVID-19 hospitalized from March 2020 to June 2021. Out of 2,249 reviewed medical records, we identified asthmatic patients and compared them with a matched non-asthmatic control group to assess asthma's impact on COVID-19 severity and outcomes.
resultsBased on the clinical records, asthma prevalence among hospitalized patients was low (1.51%); of these, 73% had allergic and 27% had non-allergic asthma. COVID-19 severity did not vary significantly between asthma phenotypes, although there was higher mortality among patients with non-allergic asthma. Most patients in both groups developed a severe form of the disease and higher mortality rates than non-asthmatics, though the differences were not statistically significant.
conclusionAsthma prevalence among patients with COVID-19 was low, but mortality was higher in asthma patients. Although the small sample size limits the generalizability of these findings, this study in a Mexican population hospitalized in a reference hospital provides insights for improving asthma management in future pandemics.
