Figure 2

Forest plots for recurrence risk of single-molecular typing after BCT in the following comparisons: ER - vs. ER+ (A), PR - vs. PR+ (B), Her-2+ vs. Her-2 - (C) and p53+ vs. p53- (D). Squares and horizontal lines correspond to the study-specific HRs and 95% CIs, respectively. The area of the squares correlates the weight and the diamonds represent the summary HRs and 95% CIs. Begg's funnel plots for publication bias for the following comparisons: ER - vs. ER+ (a), PR - vs. PR+ (b), Her-2+ vs. Her-2 - (c) and p53+ vs. p53- (d). ER, estrogen receptor; PR, progesterone receptor; Her-2, human epidermal growth factor receptor 2.
