Table 4. Model parameters describing the effects of HR, MAP and their interactions on the PPGF.

Model Parameters	Coefficients (± SEM)	P
Intercept, % (β0)	135.03 ± 23.25	< 0.001
HR, bpm (β1)	-1.02 ± 0.27	< 0.001
MAP, mmHg (β2)	-0.76 ± 0.25	0.004
HR*MAP, bpm.mmHg (β3)	0.01 ± 0.00	0.007

At any MAP level, the effect of HR can be calculated by (β3*MAP+β1)
