Quantity of nocturnal and diurnal valid blood pressure data measured by the Aktiia percent (%) and number and wearing days (nb) over the duration of the protocol. The wearing nights/days were caclulated as follows: nbr of data at 0 means = not worn, nbr of data >0 = worn. The number of nocturnal and diurnal data obtained were transmitted via the Aktiia platform algorithm, and summed over all the days in the protocol. The % of nocturnal and diurnal valid data was calculated as follows: total nb of nocturnal data measured/number of nights in the protocol, idem for diurnal.
Sleeping time (minute) per day; wearing time (%) and days (nb) of the Actigraph device per subject, over the duration of the protocol. Sleep time was obtained directly using the Actigraph platform's algorithm/data. The number of days worn was calculated by summing the days with data (0 = not worn >0 = worn), and the % of time was obtained by relating it to the total minutes over 24 h.
Minute per day and number of days of CPAP use for each patient over the duration of the protocol; N/A, no data available. The Care Orcherstrator™ platform provided information on CPAP use timeslots (start and end times of use) over one night. The sum of total minutes of use was caclulated.
