Conclusion:
Although more evidences are needed, our review showed no abnormality in
pulmonary function test in follow-up of children with a SARS-CoV-2
infection history. Disease severity and asthma background had not
confounded this outcome.
Limitation:
There are some limitations regarding present study: A) in spite of an
attempt for a comprehensive search, it maybe that some eligible articles
were missed. B) Eligible studies were observational and they were
threatened with bias in different levels. It may affect the
meta-results.
