Multivariate analysis of Age, Diameter, Lymph node status, Grade, MammaPrint and CH25H expression in relation to the M5‐15 class in the ER+HER2− NKI untreated group (N = 140).

	Variable	P value	OR	95% CI
Multivariate analysis of clinical pathological markers and CH25H expression in relation to late DM (Distant Metastasis)
M5‐15	Age (<55 yr vs ≥ 55 yr)	0.54	0.74	0.29–1.90
	Diameter (≤2 cm vs > 2 cm)	0.75	0.85	0.31–2.35
	Lymph node status (0 vs 1+)	0.004	0.12	0.03–0.50
	Grade (1 vs 2, 3)	0.47	0.70	0.27–1.84
	CH25H expression (Low vs High)	0.001	5.43	2.00–14.72

The reference class is M0.
