Table 2 Mean arterial compliance \(C_{\text{ao}}\) parameter values averaged over different samples of measurements for both model formulations and choice of data set. The p-value and 95% confidence interval (CI 95%) are obtained by a two-tailed t-test for paired data comparing the mean parameter values using the finger and carotid pressure waveforms, respectively, within the same model
