Nonparametric regression (loess) estimates calculated for the relationship between BMI and differences in PAL predicted with each equation and the measurement using the calorimeter, adjusted for age, sex, and ethnicity. Solid line (0.0) represents reference PAL measured by room calorimeter. Underpredictions fall below the reference line (AC1, AC2, AG3, and RT3), while overpredictions are above (AG1 and AG2). AC, Actical; AG, ActiGraph; PAL, physical activity level; BMI, body mass index (kg/m2).
