Summary
Companion repo to Sicbaldi et al., CinC 2024 (doi 10.22489/CinC.2024.438): Empatica E4 wrist PPG (64 Hz) + ACC (32 Hz) in-lab quiet sitting and 24 h free-living, split into wake and sleep, against Mobil-O-Graph 24 h ABPM; 23 pyPPG morphology features, low vs high BP groups and hour-by-hour trends. Data not hosted in repo → request from authors (gated). 24 h is one day, not multi-day; repeated ABPM readings within that day make it a BP-trend (diurnal) candidate.
