Using the MB-LATER score for predicting arrhythmia outcome after catheter ablation for atrial fibrillation: The Guangzhou atrial fibrillation project.

Based on net reclassification and discrimination analysis, the MB-LATER score performed best for predicting AF recurrent postablation, in a large "all comers" Chinese cohort. This simple clinical risk score (that any clinician can use in the everyday clinic) can help assess the likelihood of recurrence of AF following catheter ablation.
