Comparison between pre- and post-6MWT pulmonary function

	Pre-6MWT	Post-6MWT	P-value

IC (% predicted)	79.6±19.1	81.1 (69.3–97.0)	0.031^*
FVC (% predicted)	88.3±19.3	88.0±18.4	0.694
FEV₁ (% predicted)	68.2±23.5	68.3±23.4	0.917
FEV₁/FVC (%)	56.8 (42.4–65.2)	57.6 (46.0–66.3)	<0.001^*
SpO₂ (%)	96.0 (95.0–97.0)	97.0 (96.0–98.0)	0.020^*
Pulse (n/min)	78.0 (70.8–88.3)	98.9±15.2	<0.001^*
