Comparison of the calibrated ACEF to the LES. Being the only score that can be calibrated on a small population, the ACEF can be used with an individually defined cut off for high-risk patients. The mosaic plot shows that the areas for patients with an LES < 20% and an ACEF < 1.28 are of almost even size. Whereas the LES missed to mark one patient who later died, no patient with an ACEF < 1.28 died. Most deceased were equally identified by both risk scores.
