Table 4 showing the difference of Sn-N and N-M and sizer volume between right breast and left breast at the beginning (pre) and end (post) of surgery, their respective delta and range of deviation with p-value and correlation coefficient (R). The distance measurements are given in millimeters with their respective ± standard deviation. The volume measurements are given in cubic centimeter with their respective ± standard deviation.
