I read with great interest the article by Miró et al., [1] as the paper discusses an important aspect of clinical medicine which is of great importance in the current coronavirus disease 2019 (COVID-19) era. It is questionable as to why the authors used simplified Pulmonary Embolism Severity Index (sPESI) scores while carrying out the risk analysis of both COVID-19 and non-COVID-19 patients, irrespective of the severity of the disease, for which the patients were previously diagnosed using a computed tomographic pulmonary angiogram (CTPA).
