About

The aim of this study was to conduct a prospective randomized controlled trial to design simulator and in vitro lung standardized training, to perform a learning curve evaluation of transbronchial lung cryobiopsy (TBLC) operating physicians, and to assess the role of standardized training in TBLC.
