Index risk variables

	B	p-Value
Constant	−3.441
Cone biopsy before surgery	1.040	0.002
Approach	0.699	0.005
Preoperative image size	0.564	0.036
Score = 4 (no cone biopsy) + 3 (MIS approach) + 2 (tumor size >2 cm on imaging)

Variables were selected by stepwise analysis in the testing cohort to develop our algorithm to determine the risk of relapse, and the final score was obtained
