Systematic difference and random variance between modified Oxford baroreflex gain and transfer function modulus.

<p>Values were calculated from logarithmically-transformed data. Transfer function was obtained from random-frequency breathing. The moduli were calculated over the entire low-frequency transfer function and over the different segments of the low-frequency transfer function (see Methods).</p><p>Values are expressed as means (95% Confidence Interval). LF100 denotes the transfer function modulus calculated over the entire low-frequency band. LF75, LF50 and LF25 denote the transfer function modulus obtained from the respective percentile segments of the low-frequency transfer function (see Methods).
