6MWT parameters of subjects (n=41)

6MWD (m)	370 (328 to 445)
Minimum SpO2 (%)	90.0 (87.0 to 93.0)
ΔSpO2 (%)	−5.0 (−8.0 to −1.5)
ΔBorg	3.0 (1.0 to 4.8)

Notes: Data are presented as the median with the interquartile range. ΔSpO₂ and ΔBorg during the 6MWT were calculated by subtracting the values at baseline from those immediately after walking for 6 minutes. Borg refers to the modified Borg scale scores of subjective sense of dyspnea.

Abbreviations: ΔBorg, change in modified Borg scale scores; ΔSpO₂, change in SpO₂ values; 6MWD, 6-minute walk distance; 6MWT, 6-minute walk test; SpO₂, peripheral oxygen saturation.
