Comparison of histologic subtypes between endometrial sampling and hysterectomy specimens. A The Sankey flow diagram illustrates the distribution of histologic subtypes after endometrial sampling on the left side and the corresponding final histologic subtypes observed in the hysterectomy specimens on the right side. The lines represent the transition of histologic subtypes, with the thickness of each line indicating the number of patients. The histologic subtypes are color-coded as follows: Dark green: Endometrioid histology, Bright green: Endometrial hyperplasia, Yellow: Serous histology, Blue: Clear cell histology, Red: Carcinosarcoma, Brown: Other. B The table displays the percentage and number of cases for each histologic subtype observed after endometrial sampling (rows) and the corresponding final histologic subtype identified in the hysterectomy specimens (columns)
