Meta-analysis for prostate cancer outcomes. Forest plots show the pooled ORs and 95% CIs of TMPRSS2-ERG fusion gene with corresponding heterogeneity statistics. Squares and horizontal lines correspond to the study-specific ORs and 95% CIs; respectively. The area of the squares correlates with the weight of each enrolled study, and the diamonds represent the summary ORs and 95% CIs. Funnel plots are the assessment of potential publication bias. a Forest plot for the analysis of primary tumor; b forest plot for the analysis of adjacent lymph node; c forest plot for the analysis of metastasis; d funnel plot for primary tumor; (E) Funnel plot for adjacent lymph node; f funnel plot for metastasis; g forest plot for the analysis of biochemical recurrence; h forest plot for clinical recurrence; i forest plot for the analysis of prostate cancer-specific death; j funnel plot for the analysis of biochemical recurrence; k funnel plot for the analysis of potential publication bias of tumor-specific death
