  1. We report the amount of data recorded between the start and end of the recording as completeness. From this, we test how long the device is worn on the body, and score the signal quality of the modalities EDA, BVP, and TEMP. Additionally, we report the duration of the recorded data in h:m:s = hours:minutes:seconds.
  2. *N recordings = 832, some patients had multiple admissions and multiple simultaneous devices.
  3. †Signal quality scores are in relation to data periods estimated as on-body in the previous step.
