Estimates of PAEE, sedentary time, light PA and MVPA (mean ± SD) from EPAQ2 and combined sensing (using a standard definition of 1 MET), together with bias (95% limits of agreement (LOA)) and Spearman's correlation coefficients (rho).

PAEE: Physical activity energy expenditure; PA: Physical activity; MET: Metabolic equivalent task; MVPA: Moderate-vigorous physical activity; SD: Standard deviation.
1All bias estimates were statistically significant at P<0.001.
2All associations were statistically significant at P<0.001.
* Differences between men and women by Wilcoxon or T-test, P≤0.001.
Note, 8 hrs (assumed sleep) has been added from subjective sedentary time before calculating bias.
