Table 4 Characteristics of participants stratified according to whether they met the minimum wear time criteriaa

From: An investigation into the optimal wear time criteria necessary to reliably estimate physical activity and sedentary behaviour from ActiGraph wGT3X+ accelerometer data in older care home residents

Did participants provide 7 days with a minimum daily wear time of ≥ 8 h?
