Comment on: Smoking and quitting behavior of hospitalized COVID-19 patients

We read the article by Önder et al entitled “Smoking and quitting behavior of hospitalized COVID-19 patients” with great interest. The article is a very well-written article that emphasizes smoking behaviors in hospitalized COVID-19 patients and addresses a current and significant public health concern. Alt-hough this is a well-designed and valuable study, we would like to address some points that merit more attention.
