Analysis of the prognostic significance of PARP-1 expression levels in specific subgroups of breast cancer patients with or without H. pylori infection. Survival rate curves demonstrate that PARP-1 expression levels were significantly associated with (A) OS and (B) DFS in patients with H. pylori infection but were not significantly associated with shorter (C) OS or (D) DFS in patients without H. pylori infection. A log-rank test was performed to determine the statistical significance. *Indicated statistical significance. PARP-1, poly (adenosine diphosphate-ribose) polymerase 1; H. pylori, Helicobacter pylori; OS, overall survival; DFS, disease-free survival.
