Comparison of relative VO₂peak (A) and the systolic blood pressure/metabolic equivalent of task slope (B) using oxygen consumption measured using indirect calorimetry or estimated using American College of Sports Medicine and Fitness Registry and Importance of Exercise Database equations. Comparison of the number of individuals identified as having a systolic blood pressure/metabolic equivalent of task slope >9 mmHg per metabolic equivalent of task using indirect calorimetry vs. American College of Sports Medicine (C) or indirect calorimetry vs. Fitness Registry and Importance of Exercise Database (D).
