Kaplan–Meier curves for survival analysis of breast cancer patients based on receipt of RNI. The first row presents the Kaplan–Meier curves comparing the RNI group (blue) and no-RNI group (orange) for all patients, showing LRRFS, iDFS, and OS. The second and third rows display some of the exploratory subgroup analysis results for LRRFS and iDFS across different patient subgroups, including the tumor diameter > 2 cm subgroup (RNI group: blue, n = 67; no-RNI group: orange, n = 56); the TNBC subgroup (RNI group: blue, n = 15; no-RNI group: orange, n = 12); the TM subgroup (RNI group: blue, n = 115; no-RNI group: orange, n = 44); and the histological grade III subgroup (RNI group: blue, n = 47; no-RNI group: orange, n = 52)
