The supplementary response qualifies the detector result: its current blood-pressure calibration is subject-specific, and calibration-free transfer is challenged by inter-subject and within-person variability. DIRECT_TEXT

The calibration procedure is indeed subject-specific, a detail that we now explicitly clarify in the revised manuscript. Transitioning our specific model to a calibration-free framework presents significant challenges. Because cuffless BP estimation models ... involve a multitude of parameters. These parameters exhibit high inter-subject variability and can also fluctuate situationally within the same individual.
