Survival curves stratified by the combination tool using the expression of PgR and Ki67. a Relationship between the Ki67 labeling index and cancer-specific survival (CSS). b Survival curves stratified by PgR expression according to staining percentages in the intermediate Ki67 labeling index (Ki67 > 10 and <30%) group. Comparisons of CSS between the PgR-positive (≥20%) and PgR-negative (<20%) groups
