Survival analysis of oral leukoplakias based on the cure model

Variables	Estimate	SD	HR	2.5 Q	97.5 Q
(Intercept)	− 9.09	1.33	-	− 11.78	− 6.66
Clinical type (non-homogeneous)	0.86	0.48	2.37	0.94	6.35
Histology (high-grade dysplasia)	1.16	0.53	3.19	1.05	8.59
Size	0.015	0.01	1.02	0.98	1.04
Location tongue	1.57	0.60	4.78	1.60	16.61
Location gingiva	− 1.21	0.81	0.30	0.05	1.26
Treatment (laser)	− 0.47	0.52	0.63	0.23	1.73
Tobacco	− 0.01	0.48	0.99	0.38	2.45
Cure fraction	0.27	0.09	-	0.16	0.48

Estimates for the effects of the different variables are presented along with their standard errors, Hazard ratios and their corresponding 95% confidence intervals. The models also provide an estimate for the cure fraction, which stands for the estimated proportion of the patients that will never experience MT
