[1] where the authors performed an interesting study to evaluate the effect and feasibility of pulmonary rehabilitation (PR) in coronavirus disease 2019 (COVID-19) patients. However, we feel that a few pertinent issues need to be highlighted and addressed. COVID-19-associated chronic health issues can persist for a prolonged period after recovery from acute illness and have been termed “long COVID”. However, the literature suggests that computed tomography changes and associated lung function impairment show resolution with time [2].To evaluate the benefit of pulmonary rehabilitation, a control group is a must to mitigate the effect of confounding factors like spontaneous resolution of lung damage, learning effect and better mental status https://bit.ly/3qy5sfe ER -
