In Reply First of all, we would like to thank Dr Ghadami for his interest and comments on our research. 1 And also, we agree with his opinion that sleep problems may contribute to the development of depression and anxiety in patients with chronic rhinosinusitis (CRS). Importantly, as we emphasized in our research, we found that patients with CRS without nasal polyp showed a higher risk of developing depression and anxiety than those with CRS with nasal polyps. However, we could not compare the degree of sleep impairment between patients in the 2 groups because the database used does not provide information from sleep-related medical charts or polysomnography data. For these reasons, we could not suggest sleep problems as a possible cause in this study.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
