Study limitations:
One of the important limitations of the study is the modest sample size and the heterogeneity of population group studied. Since a significant proportion of severe COVID-19 patients succumb to the illness, patients surviving COVID-19 infection might not reflect the true severity of the disease leading to a survival bias. Lastly, a longer duration of follow-up is needed to determine the sequence of evolution of CMR changes in COVID-19 recovered subjects and long-term prognostic implications.
