Key Points

To clarify the data presented in Table 1 regarding pulmonary and functional outcomes after SARS-CoV-2 infection across different severity groups.
Observed patients categorized using WHO severity criteria.
Corrected numerical data in Table 1 for gender representatives on pulmonary function outcomes.
No new analyses were introduced as a part of the correction.
The corrected value for male and female participants in Table 1 is updated from 26 to 27 with no change in percent.
Clarified phenotypes for mild (G1), moderate (G2), and severe disease (G3) remain as previously described.

Abstract

There was a mistake in table 1as published. In the published article, there was a mistake in the Table 1. For both male and female participants, the table currently reports the value 26 (50%).The correct value in both cases should be 27 (50%). The corrected table 1 appears below. a, The period during which patients are admitted to a regular hospital ward for monitoring and treatment of their clinical condition; b, The period during which patients are admitted to the intensive care unit for more intensive monitoring and treatment due to the severity of their clinical condition; c, The period during which patients are under care in the emergency room or primary health care unit for acute management or initial treatment before being discharged or transferred for further care.Disease severity was determined by a physician, according to World Health Organization criteria. The G1 phenotype was characterized by mild to moderate clinical symptoms, with possible radiological findings or the presence of pneumonia on chest computed tomography. The G2 phenotype was characterized by respiratory distress and/or hypoxia/hypoxemia, while the G3 phenotype involved respiratory failure requiring mechanical ventilation, shock, and/or multiorgan dysfunction (5,16).The original version of this article has been updated.Thank you for your attention. We remain at your disposal should any additional information or clarification be required.Sincerely, Patricia Blau Margosian Conti UNICAMP pbmc@unicamp.br
