Re: Prevalence Of Pulmonary Embolism In Ed Patients With Suspected Covid-19: The Truth Remains Unknown

We thank « John Doe » et al. for their interest and comments on our paper \"Association between Pulmonary Embolism and COVID-19 in ED patients: the PEPCOV international retrospective study\". The authors raised the important issue of a possible bias, because we only analyzed patients that were tested for pulmonary embolism (PE) with computed tomography pulmonary angiogram (CTPA). We acknowledge that this is a limitation, and accordingly highlighted in our manuscript that whether these results apply to the general population is unknown.
