Table 2.

Multivariate (MANOVA) and Univariate (ANOVA) analyses of variance F ratios for CrN × CrTot effects for PEFR and %CEV.

	MANOVA	ANOVA
		PEFR	%CEV
	CrN: F(12, 398)	CrN: F(6)	CrN: F(5)
	CrTot: F(10, 398)	CrTot: F(6)	CrTot: F(5)
	CrN × CrTot:	CrN × CrTot:	CrN × CrTot:
	F(30, 398)	F(15)	F(15)
CrN (Cough number)	37.084**	25.135**	110.401**
CrTot (Total coughs)	11.061**	15.914**	17.418**
CrN × CrTot	2.133*	0.620	4.131**

Only those measures with significant p-values are included.

Note: MANOVA F ratio is Wilks' Lambda approximation of F. PEFR is peak expiratory flow rate; %CEV is percent cough expired volume.

^*p = 0.001;

^**p < 0.001.
