Fig. 6From: A prospective comparison of ER, PR, Ki67 and gene expression in paired sequential core biopsies of primary, untreated breast cancera Funnel plot for 24 studies on ER concordance between diagnostic cores and surgical specimen. Mean concordance is 92.38 %. Excluding the seven studies that fall outside the 99 % Confidence Interval, changed the mean to 95.63 %. b Funnel plot for 19 studies on PgR concordance between diagnostic cores and surgical specimen. Mean concordance is 84 %. Excluding the two studies that fall outside the 99 % Confidence Interval has not changed the mean. c Funnel plot for five studies on Ki67 concordance between diagnostic cores and surgical specimen. Mean concordance is 67.4 %. Excluding the study that fall outside the 99 % Confidence Interval, changed the mean to 69.75 %Back to article page
