Indicator, proportion of	Observed value (%)	Reference value (%)
Surgical intervention for malignant disease	79	≥67
Patients with axillary lymph node status determined with the SN technique	97	>95
Patients with ten or more nodes excised in axillary dissection	96	>95
Patients with complete reporting of data	92	>95
High-risk patients allocated to adjuvant treatment according to the guidelines	89	–a
Patients completing the follow-up program according to the guidelines	82	>95
