ROC was used to assess the sensitivity, specificity and diagnostic accuracy of identified risk factor, for predicting the CR failure. The pre-op AI has better sensitivity (0.783), specificity (0.740) and diagnostic accuracy (84.1%) than pre-op AI (0.639; 0.700; 68.8%) and age (0.651;185 0.603; 65.0%) for predicting the CR failure
