there were no consistent, statistically significant associations with CVD risk or mortality (CVD related and all-cause) (Table4). This can be explained by the magnitude of difference in systolic blood pressure observed
This can be explained by the reduced SNR of the sub-regions compared to the SNR of the entire ROI. Our method is not much affected by noise in the individual PPG wave- forms since the algorithm searches for the signature that provides the best SNR, even though it may be quite low. ...
