Logistic regression and ROC analysis. a L4/5: a cutoff value of 15.5 months at which classification according to fixed time yields a sensitivity of 100% and specificity of 60%. The area under the curve AUC is 0.80. b L5S1: a cutoff value of 21.0 months at which classification according to fixed time yields a sensitivity of 89% and specificity of 89%. The area under the curve AUC is 0.80
