Patients and controls were divided into normolipemics and different types of hyperlipoproteinemia according to Fredrickson. The table lists the percent of patients and controls with Lp(a) above the three indicated cut-off values. The RRs were calculated from percent of MI patients divided by the percent of controls belonging to the corresponding groups. The table was adapted from (12). See main text for details. n.d., not determined.
