Methodological considerations in the study of quality of life after slide tracheoplasty for congenital tracheal stenosis

We read with great interest the article “Quality of Life and its Clinical Determinants After Slide Tracheoplasty for Congenital Tracheal Stenosis” by Nakatani and colleagues [1]. The study provides valuable insight into the long-term outcomes of pediatric patients undergoing slide tracheoplasty, particularly regarding quality of life (QOL) and voice function. However, we would like to raise several methodological and interpretative considerations.
