Effectiveness of Second through Sixth Line Salvage Helicobacter pylori Treatment: Bismuth Quadruple Therapy is Almost Always a Reasonable Choice

Figure 2

Patient enrollment. Patients referred for salvage therapy were initially enrolled after failing 1–5 attempts at H. pylori therapy with their referring physician. Salvage therapy was offered within this study as second to sixth attempts and those failing these attempts were offered subsequent salvage therapy within the study. The “failed to eradicate” numbers in the figure refer to those failing therapy and continuing to participate in the next treatment attempt.
