Comparisons of the performance of exercise test between Kawasaki group 1 and 2. Legend: Among all the routined measured variables during cardiopulmonary exercise testing, KD group 1 had significantly higher a peak VO2 Z-score, peak PD%, peak MET, and b PRPP than the KD group 2. Peak VO2 Z-score, Z-score of peak oxygen consumption based on reference value; Peak PD%, measured peak oxygen consumption divided by predicted peak oxygen consumption; KD, Kawasaki disease; KD group 1: Max-Z of coronary artery less than 2.5; KD group 2: Max-Z of coronary artery equals to or more than 2.5; MET, metabolic equivalent; AT MET, MET at the point of anaerobic threshold; peak MET, largest MET during whole exercise testing; HR, heart rate; peak PD, percentage of predicted peak MET; VE, minute ventilation; peak RER, largest respiratory exchange ratio during whole exercise testing; SBP, systolic blood pressure; DBP, diastolic blood pressure; PRPP, peak rate pressure product; HRR at one minute, heart rate reserve at one minute after termination of the test
