Accelerometer-derived number of steps taken in trips according to the main modea used in the trip
| Classifications of trips according to the mode | Number of steps taken per trip: median (10th and 90th percentiles) | Cumulated number of steps in trips per individual per 8 h of accelerometer wear time:b median (10th and 90th percentiles) | % of trip-related steps taken attributable to these trips |

RECORD MultiSensor Study, 284 participants, 8728 trips, 20,564 trip stages
aWe consider the steps accumulated over the entire trip (including with non-walking modes and during transfer episodes)
bThe overall number of days of mobility survey could not be used as the denominator as there is nonwear of the accelerometer within it. As a consequence, we chose as the denominator the number of units of 8 h of accelerometer wear time
