Notes:
a
Median and quartiles were calculated for continuous data, and absolute numbers and percentages were computed for nominal variables.
b
The MET, or simply metabolic equivalent, is a physiological measure expressing the energy cost of physical activities, and is defined as the ratio of metabolic rate (and therefore the rate of energy consumption) during a specific physical activity to a reference metabolic rate.
Abbreviations: HF, heart failure; MET, metabolic equivalent of task.
