One way sensitivity analysis of Markov model evaluating cost effectiveness of Helicobacter pylori eradication treatment for non-ulcer dyspepsia

Variable altered	Worst case scenario for H pylori eradication				Best case scenario for H pylori eradication
	Extra cost (£)*	Extra benefit (symptom-free months)†	Incremental cost effectiveness (£)‡		Extra cost (£)*	Extra benefit (symptom-free months)†	Incremental cost effectiveness (£)‡
Cost of visit to general practice	33.61	0.563	60		31.35	0.563	56
No of visits to general practice per year if dyspeptic	33.45	0.563	59		24.16	0.563	43
Cost of antacid treatment	32.56	0.563	58		21.74	0.563	39
Cost of H pylori eradication treatment	33.14	0.563	59		9.18	0.563	16
Relative risk of dyspepsia with eradication treatment	33.79	0.256	132		29.79	0.856	35

^*Cost of H pylori eradication−antacid strategy. 

^†Extra months free from dyspepsia with H pylori eradication compared with antacid strategy. 

^‡Incremental cost of H pylori eradication compared with antacid strategy per month free from dyspepsia.
