Table 7. Predictive inaccuracy, explained variation and area under curve for 10-years survival in the Dutch dataset.

	Predictive inaccuracy	Explained variation (%)	AUC
Model without predictors	0.393±0.017	−	0.701 [0.634;0.769]
Model with histological type	0.393±0.017	0.0±0.5	0.701 [0.634;0.769]
Model with surgery	0.392±0.017	0.3±0.9	0.707 [0.641;0.774]
Model with HER2	0.396±0.019	−0.6±2.1	0.700 [0.631;0.769]
Model with mitotic index	0.367±0.023	6.7±3.2	0.738 [0.674;0.802]
Model with genomic signature	0.342±0.019	13.1±3.6	0.775 [0.718;0.832]

All models are estimated taking into account Adjuvant! Prediction as an offset. Data are presented as the mean ± standard error.
