Table 3 Differences in the eradication effect on the rate of increase in haemoglobin level between groups of patients with < haemoglobin 12.5 g/dL (n = 20) and patients with ≥ haemoglobin 12.5 g/dL (n = 96)

Variable	Subjects	Missing	Pre-eradication mean (SD)	Post-eradication mean (SD)	Mean difference	95%CI	P value
Less than Hb 12.5 g/dL	19	1	11.5 (0.7)	12.3 (1.0)	0.85	0.22-1.48	0.017
More over Hb 12.5 g/dL	96	11	14.2 (1.1)	14.1 (1.2)	-0.15	-0.1592	0.064
