Comparison of outcomes of the two different surgical approaches within the first 3 years following surgery for all patients and the subgroup of node-negative patients, respectively

Outcome	No. of events within 3 years	IPTW-adjusted 3-year Kaplan-Meier rates, % (95% CI)		IPTW-adjusted HR for SLN vs. LND
Outcome	No. of events within 3 years	SLN cohort	LND cohort	HR (95% CI)	P
All patients
Death	29	87.9 (79.9, 96.7)	76.8 (67.1, 87.9)	0.44 (0.19, 1.02)	0.06
Recurrence	43	68.9 (57.8, 82.2)	80.3 (70.9, 90.9)	1.46 (0.70, 3.04)	0.32
Node-negative patients
Death	17	88.5 (79.7, 98.2)	86.4 (77.9, 95.9)	0.69 (0.24, 1.95)	0.48
