Cross-sectional evaluation of patients with refractory or unexplained chronic cough by office-based pulmonologists in Germany

This study, the first in a secondary care setting in Germany to determine RCC/UCC prevalence in outpatients, found a higher prevalence in women and a long history of suffering. These findings underscore the need for improved diagnostic procedures and new therapeutic developments for RCC/UCC. Key limitations include the potential impact of the Covid-19 pandemic on data collection, a relatively small UCC sample, and potential referral bias due to the secondary care setting.
