Fig. 4From: Surveillance cardiopulmonary exercise testing can risk-stratify childhood cancer survivors: underlying pathophysiology of poor exercise performance and possible room for improvementScatter graphs with peak minute ventilation (pVE) in x-axis and peak oxygen consumption (pVO2) in y-axis to assess the ventilatory efficiency for oxygen uptake in CCS. A. Males, and B. Females. Normal performers showed slightly better pVO2 with the same pVE, suggesting their slightly better oxygen uptake efficiency than Poor performers in both sexesBack to article page
