Ratio of predicted risk to observed risk between the low-risk and high-risk subgroups. Pred: predicted risk, obs: observed risk. *: the difference between predicted and observed risk was not significant (p = 0.099). The Adjuvant! Online model showed a good discriminative performance in the low risk patients. +: the difference between predicted and observed risk was significant (p = 0.016). The Adjuvant! Online model showed an overestimation of observed 10-year breast cancer-specific survival in the high risk patients.
