Physiology-based identifiable model-quantity subset selection for early prediction of intradialytic mean arterial pressure trajectories from sparse observations

andranges from 88.74% to 91.83% across the four phenotypes. Prediction-phase root-mean-square error ranges from 1.09 to 5.78 mmHg, and the maximum error ranges from 1.71 to 8.51 mmHg. This patient-type-level framework enables interpretable MAP trajectory prediction and provides a methodological basis for future patient-level evaluation of IDH-related MAP decline.
