Performance of the GTFs and ITFs in terms of the errors associated with the estimation of central BP from diametric PVR waveforms in training data.
| Training (N=50) | RMSE [mmHg] | SP Error [mmHg] | PP Error [mmHg] | SP & PP Error Norm [mmHg] |
|---|---|---|---|---|
| (a) GTF | ||||
| Arm TLG GTF | 4.39* | 4.92* | 4.35 | 6.57* |
| Arm TLS GTF | 3.70 | 3.52 | 3.84 | 5.21 |
| Ankle TL GTF | 3.96 | 4.35 | 4.65 | 6.37 |
| (b) ITF | ||||
| f-ITF | 3.83 | 5.37 | 5.02 | 7.36 |
| p-ITF1 | 2.11† | 2.01† | 3.08† | 3.68† |
| p-ITF2 | 2.43† | 2.18† | 3.31† | 3.96† |
Errors are root-mean-squared across all subjects. SP: systolic pressure. PP: pulse pressure. SP & PP Error Norm: Euclidean norm of SP and PP errors. *Significantly different from the arm TLS GTF (p < 0.05 with Holms-Bonferroni correction). †Significantly different from the f-ITF (p < 0.05 with Holms-Bonferroni correction).
