^a, based on negative ranks; ^b, Wilcoxon signed ranks test. D1: maximum length diameter of the largest surface of the tumor bed measured by eyes; D2: maximum short diameter of the largest surface of the tumor bed measured by eyes; d1: maximum length diameter of the largest surface of the tumor bed measured by CXS; d2: maximum short diameter of the largest surface of the tumor bed measured by CXS; H1: maximum length diameter of the largest surface of the tumor bed measured by microscope; H2: maximum short diameter of the largest surface of the tumor bed measured by microscope. CXS, cabinet X-ray system.
