Table 5.

Comparison of area-under the curve (AUC) pre versus post-mouthwash (n = 69).

	Mean AUC (SD)		Mean difference (SD)	p value^a
	Pre-mouthwash	Post-mouthwash	Mean difference (SD)	p value^a
Hydrogen	65.5 (61.9)	45.3 (39.2)	20.2 (28.1)	< 0.001
Methane	112.4 (91.2)	76.2 (61.7)	36.2 (35.1)	< 0.001
Hydrogen + methane	177.9 (90.3)	121.9 (62.5)	56.0 (40.8)	< 0.001
