Follow-up studies in COVID-19 recovered patients - is it mandatory? This study was approved by the ethics committee of Ludwig-Maximilians-University, Munich, Germany and adhered to the tenets of the Declaration of Helsinki. Since COVID-19 shows more severe courses in older patients, findings of decreased vessel density might not be due to past inflammatory processes, but rather represent normal age related alterations [41]. https://doi.org/10.1038/s41591-021-01283-z (2021).
