Forrest plot for relative risk of recurrence by extranodal extension status. First of all we present the data about risk of biochemical recurrence (papers of Fleischmann et al., and of Passoni et al.), then their meta-analyzed values (pooling data), then the data about risk of metastasis (Cheng et al.), its mean (only this study about the risk of metastasis, so we repeat this value), then the overall meta-analysis of these data (meta-analysis of all these papers about risk of recurrence – both biochemical and metastasis).
