Bland–Altman plots depicting the differences between TFD measured in hysterectomy specimen (pTFD) versus by MRI (iTFD) showing best agreement between pTFD and iTFD for the low TFD values (a-c). Mean pTFD (n = 230) was 1.79 mm larger than mean iTFD (a); when based on macroscopic assessment mean pTFD (macro) (n = 210) was 2.18 mm larger than iTFD (b) and when based on microscopic assessment mean pTFD (micro) (n = 85) was 0.08 mm larger than mean iTFD (c). In patients having recordings on both pTFD (macro) and pTFD (micro) (n = 65), mean pTFD (macro) was 1.14 mm larger than mean pTFD (micro) (d). pTFD = tumor-free distance reported in routine pathology report; iTFD = MRI-assessed tumor-free distance to serosa; pTFD (macro) = tumor-free distance to serosa based on macroscopic assessment; pTFD (micro) = tumor-free distance to serosa based on microscopic assessment; SD = standard deviation
