Table 5 . Intention-to-treat and per-protocol eradication rates in three treatment regimens .

Total enrolled patients(n=372)	Group A(OABF) (n=124)	Group B(OABM-F) (n=124)	Group C(OAF) (n=124)	p
Number of patients who have consumed >80% of drugs	120	120	116
ITT* eradication rate with 95% CI (n=372)	83.7% (104/124) (95%CI=77.3-90.4)	79.8% (99/124) (95%CI=72.6-87.0)	84.6%(105/124) (95%CI=78.2-91.1)	0.557
PP* eradication rate with 95% CI(n=356)	86.6% (104/120)- (95%CI=80.5-92.8)	82.5% (99/120) (95%CI=75.6-89.4)	90.5%(105/116)-(95%CI=85.1-95.5)	0.197

The cure rates was higher in treatment regimen C(OAF), but in general, the differences were not statistically significant (p=0.197, p=0.557, respectively for PP and ITT) and therefore, as far as helicobacter pylori eradication level is considered, the treatment regimen C(OAF) is in Grade B (good), and treatment regimen B(OABM-F) is in Grade D (poor) and treatment regimen A(OABF) is in Grade C (moderate or acceptable).
