Figure 3.

Comparison of TDEE between DLW (reference-standard method) and SWA, FLEX-HR, PARA-SCI, and PASIPD (predictive methods). TDEE = total daily energy expenditure; DLW = doubly labelled water; SWA = SenseWear Armband; FLEX-HR = Flex heart rate monitoring; PARA-SCI = Physical Activity Recall Assessment for People with Spinal Cord Injury; PASIPD = Physical Activity Scale for Individuals with Physical Disabilities. Shown in the legend are the coefficients of determination (R²) between DLW-derived TDEE and predicted TDEE.
