Key result
Four different spectral analysis techniques yielded non-significant mean differences in baroreflex gain estimates, ranging from 0.074 to 0.298 ms mmHg-1 in the MF band.

Baroreflex gain estimates appear robust to spectral method choice in healthy subjects; leaves open generalizability to patients or other conditions.
Cross-Sectional (n=10)
Do different spectral analysis techniques significantly affect estimates of baroreflex gain in healthy subjects?
The use of different spectral analysis techniques (FFT, FFTZ, ACVF, ME) does not significantly affect estimates of baroreflex gain.
Clayton et al. (1995) conducted a cross-sectional in Healthy (n=10). Spectral analysis techniques (FFT, FFTZ, ACVF, ME) vs. Each other was evaluated on Differences in estimates of baroreflex gain (alpha) in MF and HF bands. Four different spectral analysis techniques yielded non-significant mean differences in baroreflex gain estimates, ranging from 0.074 to 0.298 ms mmHg-1 in the MF band.
