Table 2.

Breath methane and stool methanogen levels before and after antibiotic therapy

	Methane Eradicators (n=8)			Methane Non-Eradicators (n=3)
	Pre-Ab	Post-Ab	P-value	Pre-Ab	Post-Ab	P-value
Stool methanogens	3.6×107	1.1×105	0.16	6.86×108	9.4×107	NS
Stool total bacteria	1.1×109	1.2×109	NS	3.7×108	8.5 ×109	NS

Pre-Ab = before antibiotic therapy; Post-Ab = after antibiotic therapy.

^*P-value is comparing change in methane eradiacators before and after treatment to change in methane non-eradiacators before and after treatment.

NS=not significant.
