  1. AVB IVCD denotes atrio-ventricular and intra-ventricular conduction disturbances according to standard (conservative) criteria (n = 21).
  2. AVB IVCDx denotes such disturbances according to less conservative criteria (n = 31) for comparison with ref.[13].
  3. PQ interval = duration from P-wave to QRS complex; QRS interval = duration of QRS complex; AVB = atrio-ventricular Block; IVCD intra-ventricular conduction disturbances; WBC White Blood Cells (×109/L).
  4. Beta regression coefficient; CI confidence interval; OR = odds ratio.
  5. Multivariate analyses (forward stepwise multivariate linear regression and logistic regression).
