Fig. 2From: Exercise Training in Heart failure with Preserved and Reduced Ejection Fraction: A Systematic Review and Meta-AnalysisExercise capacity (peak VO2 and 6MWD) forest plots for both HFpEF and HFrEF. Asterisks signify statistical significance (P < 0.05). HFpEF, heart failure with preserved ejection fraction; HFrEF, heart failure reduced ejection fraction; VO2, volume of oxygen uptake; and 6MWD, six-minute walk distanceBack to article page
