Table 3.

Proportion of Luminal A tumours, according to molecular subtyping, in subgroups generated by combining histological grade (HG1–3) and Ki67 in three categories (according to Maisonneuve et al. [12])

Ki67	HG1	HG2	HG3
Low (< 14%)	97% Luminal A (n = 211 of 218)	95% Luminal A (n = 282 of 297)	88% Luminal A (n = 7 of 8)
Intermediate (14–19%)	89% Luminal A (n = 116 of 130)	86% Luminal A (n = 255 of 298)	53% Luminal A (n = 8 of 15)
High (≥ 20%)	87% Luminal A (n = 96 of 110)	64% Luminal A (n = 389 of 607)	25% Luminal A (n = 94 of 380)
Total	92% Luminal A (n = 423 of 458)	77% Luminal A (n = 926 of 1202)	27% Luminal A (n = 109 of 403)
