Table 7. Portal release half-life of XPP peptides—Effect of a meal matrix.

					Statistics
Matrix	group	IPP (min)	LPP (min)	VPP (min)		Matrix/diet effect	XPP effect	Interaction		Macronutrient effect
*protein*	CasH2	47±7^*	49±9^*	45±7^*	p¹	<0.0001	0.977	0.916
*meal*	Basal	125±19	116±21	125±21	p²	<0.0001	0.797	0.997
	LQprot	85±12	76±13	78±13					p³	0.009
	hCHO	112±16	113±21	122±19					p³	0.970
	hFat	166±17	168±15	155±22					p³	0.014
	Fiber	136±10	114±19	129±18					p³	0.997

Time after administration when 50% of total portal tri-peptide release (net balance) has occurred (t_½,r in min). Values are mean ± SEM. (Basal, LQprot, hFat: n = 10; CasH2, hCHO: n = 9; hCHO: n = 7) Significance: p<0.05.

^p¹: significance for comparison of comparing protein matrix with meal matrix: Two-way ANOVA.

*): p<0.05 significance for comparison IPP, LPP or VPP portal release half-life of CasH2 relative to Basal with post-hoc Sidak’s multiple comparison test.

^p²: significance for comparison meal matrixes: Two-way ANOVA.

^p³: significance for macronutrient effect (LQprot, hCHO, hFat, or Fiber meal vs Basal) with post-hoc Dunnett’s multiple comparison test.
