Although PSP typically occurs in young, thin, healthy males, the chest anthropometrics in PSP remain insufficiently explored. We aim to evaluate the chest anthropometrics and smoking habits of patients with PSP compared to healthy volunteers.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>METHODS:<\/jats:title>\n                    <jats:p>Fifty-eight adult male participants (38 PSP patients and 20 healthy volunteers) aged between 18 and 30 years were included. The study focused on thoracic anthropometric measurements, including body mass index (BMI), height, weight, circumference, sagittal, transverse diameters, and chest height.
