The asterisk (*) signifies an interaction between variables. N is the number of days entering the individual models. ACC average acceleration in milligravitational units (mg) represents the volume of physical activity, IG intensity gradient represents the intensity of physical activity, MVPA minutes of moderate to vigorous physical activity, BMI body mass index, NA not assessed, i.e., the covariate was not included in the final model
