Fig. 1From: ACEF performed better than other risk scores in non-ST-elevation acute coronary syndrome during long term follow-upEvent-free survival for MACE: a ACEF tertiles (T1/T2 vs. T3); b Optimal prognostic cut-off value*. T1—ACEF risk score first tertile (values < 1.00); T2—ACEF risk score second tertile (values 1.00–1.24); T3—ACEF risk score third tertile (values > 1.24); *determined by Youden index (< 1.19 vs. > 1.19)Back to article page
