Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
To determine the prevalence and types of spirometry abnormalities among post-COVID-19 patients in Malaysia, with secondary objective focusing on associated factors. Conducted at the COVID-19 Research Clinic, Faculty of Medicine, University Technology MARA, from March 2021 to December 2022, this study included patients three months post-discharge from hospitals following moderate-to-critical COVID-19. Of 408 patients studied, abnormal spirometry was found in 46.8%, with 28.4% exhibiting a restrictive pattern, 17.4% showing preserved ratio impaired spirometry (PRISm), and 1.0% displaying an obstructive pattern. Factors independently associated with abnormal spirometry included older age (OR 1.0, 95% CI 1.01–1.04, p = 0.003), underlying cardiovascular disease (OR 3.5, 95% CI 1.19–10.47, p = 0.023), history of acute respiratory distress syndrome (p < 0.001), shorter discharge-to-follow-up interval (OR 0.9, 95% CI 1.00–1.02, p = 0.035), oxygen desaturation during 6-minute walk test (OR 1.9, 95% CI 1.20–3.06, p = 0.007), and presence of consolidation (OR 8.1, 95% CI 1.75–37.42, p = 0.008) or ground-glass opacity (OR 2.6, 95% CI 1.52–4.30, p < 0.001) on chest X-ray. This study highlights patients recovering from moderate-to-critical COVID-19 often exhibit abnormal spirometry, notably a restrictive pattern and PRISm. Routine spirometry screening for high-risk patients is recommended.
