rPPG quality recording exclusion criteria.

rPPG quality metrics	Minimum values
IBI coverage (%)	83
Average pulse quality index	0.85
Median pulse quality index	0.90
Percentage of pulses with quality index > 0.6 (%)	89
25th percentile pulse quality index	0.80
75th percentile pulse quality index	0.96

These metrics were calculated for each 30-s epoch and averaged for each recording. We considered the recordings not satisfying one or more of the minimum values characterized by low rPPG quality.
