Figure 1From: Oxygen kinetics during 6-minute walk tests in patients with cardiovascular and pulmonary disease Study exclusions due to technical issues or loss of follow-up. Nine (3%) tests were excluded due to significant patient-related or technical flaws. In thirty-eight (15%) tests it was not possible to fit an acceptable oxygen uptake kinetics curve. Two hundred and twenty tests (82%) were included in the final analysis.Back to article page
