Figure 4.

Forest plots of receptor conversions for each receptor expression subtype in the brain metastasis compared to the primary tumor: (A) ER gain; (B) ER loss; (C) PR gain; (D) PR loss; (E) HER2 gain; (F) HER2 loss. Squares indicate the proportions from individual studies and horizontal lines indicate the 95% confidence interval. The size of the data marker corresponds to the relative weight assigned in the pooled analysis using the random effects model. Diamond indicates the pooled proportion with 95% confidence interval.
