The P-values were obtained from the type III test for the fixed effect of criteria being used.
Use of “Wear Time” in column headings is used for brevity to indicate “registered time as an indicator of wear period”.
Sample size changes for bout duration and intensity for the 2 categories as compared to number of bouts since all participants’ data are included in the number of bouts, but only those that met the specific criteria (ex. ≥6 METS for ≥ 10 minutes) are included in the bout duration and intensity. For each specific bout definition, sample size is the same for bout duration and intensity, which signifies the number of participants that met that criterion.
