Abstract

Background The distance–saturation product (DSP), calculated by multiplying 6-min walk distance (6MWD) by lowest oxygen saturation, is a composite physiological marker of exercise capacity and gas exchange impairment. Although DSP has shown prognostic potential in Western COPD cohorts, its utility and optimal threshold in Asian populations remain unestablished. This study evaluated whether DSP
