MAPE according to the number of valid days defined as accelerometer wear time ≥ 2/3 of both day and night periods (Scenario 2)*. Abbreviations: mean absolute percent error (MAPE), inter-daily stability (IS), intradaily variability (IV), transition probability (TP), TP from activity to rest during the day (TP_{ar, d}), TP from wake to sleep during the night (TP_{ws, n}), TP from rest to activity during the day (TP_{ra, d}), TP from sleep to wake during the night (TP_{sw, n}), and activity balance index (ABI). Bold values correspond to MAPE ≤ 15%
