Abstract
This letter to the editor presents key concepts on research designs, prevalence and incidence, as well as statistics for comparing dichotomous variables, highlighting the difference with likelihood ratio. A Chi2 exercise with the study data is included to illustrate the methodology. Finally, a brief description of the pathophysiological mechanism linking COVID-19 infection with pulmonary thromboembolism is provided.
