The subgroup analysis assessed the association between TMPRSS2-ERG fusion subtypes and prostate cancer. Forest plots show the subgroup analyses of deletion-type fusion versus other fusion types. Squares and horizontal lines correspond to 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 indicate the assessment of the potential publication bias. a forest plot for the subgroup analysis of different races; b funnel plot evaluating the heterogeneity for the subgroup analysis in different races; c forest plot for the subgroup analysis in metastatic PCa or CRPC; d funnel plot for the subgroup analysis in metastatic PCa or CRPC
