Association between aerobic capacity and emphysematous changes.
<p>The aerobic capacity at peak exercise (peak </p><p></p><p></p><p></p><p>V<mo>Ë™</mo></p><p></p><p></p><p></p>o<sub>2</sub>) was inversely correlated with total LAA scores (p<0.0001, r = -0.485).<p></p
Association between emphysematous changes and oxygen desaturation during exercise.
<p>The oxygen saturation (SpO<sub>2</sub>) at the peak exercise was inversely correlated with total LAA scores (p<0.0001, r = -0.634).</p
