Variable	Unit Reference	HR (95% CI)	p-value*
Age	10 year	0.93 (0.63,1.39)	0.74
FULV. dose	500 vs. 250mg	0.95 (0.79,1.15)	0.63
ER levels	1-unit increase in Allred score**	1.00 (0.92,1.08)	0.92
PR levels	≥6 / <6 Allred score	0.59 (0.38,0.91)	0.016
HER2 status	3 / 0–2 IHC	1.91 (1.04,3.52)	0.037

^*Hazard ratio (HR) and 95% confidence interval (CI) are from a univariate Cox model, p-values are from a Wald-type hypothesis test.

^**ER was not significant (p > 0.5) for all possible cutpoints in Allred score.
