Fig 1. Bland-Altman plots showing energy expenditure agreements between accelerometers and behavior mappings.

Filled circles (•) show behavior mappings. Open circle (○), triangle (Δ), and square (□) represent sedentary (< 1.6 METs), light (1.6–2.9 METs), and moderate (3.0–5.9 METs) activities from acccelerometers. Vigorous (≥ 6 METs) activity was not observed. Behavior mapping showed the strongest agreement with energy expenditure (PAEE) of bUL+bLL without proportional bias (R² = 0.003, p = 0.052, Fig 1I). A relatively better agreement was observed in lower intensities than that in higher intensities. Dotted lines represent mean ± 1.96 SD of difference in PAEEs. Lightface lines represent regression line for difference in PAEEs.
