Forest plots for efficacy, hazard ratio for A) disease-free survival (DFS), B) overall survival, C) DFS by nodal involvement (negative or positive), and D) DFS by estrogen receptor status (positive or negative). Hazard ratios for each trial are represented by squares, the size of the square represents the weight of the trial in the meta-analysis, and the horizontal line crossing the square represents the 95% confidence interval (CI). The diamonds represent the estimated pooled effect. All P values are two-sided.
