Figure 3

Comparing the physical activity and total energy expenditure estimates of highly adherent subjects (24 HR; n = 35) to activity monitor removal simulations. Simulation A2: simulation of activity monitor removal during sleep by imputing zeroes and during 1 and 10 waking hours (zeroes imputed in the place of the raw data). Simulation B2: simulation of compensating for activity monitor removal during sleep by measuring waking hours only (sleeping physical activity deleted), and during 1 and 10 waking hours (zeroes imputed in the place of the raw data). Simulation C2: simulation of compensating for activity monitor removal during sleep by imputing a constant (23.1 counts/min), and during 1 and 10 waking hours (zeroes imputed in the place of the raw data). Simulation D: simulation of compensating for activity monitor removal during sleep by imputing a constant (23.1 counts/min), and during 1 and 10 waking hours (imputing estimates in the place of the raw data).
