In all analyses, we modeled Lp(a) concentrations as quartiles to avoid the
assumption of linearity and to reduce the effects of outliers. Furthermore, we
used median Lp(a) concentrations for the categories to test for linear trends
across quartiles. We categorized the data according to the 90th, 95th, and 99th
percentiles and performed threshold analyses. We also used the test of Hosmer
and Lemeshow to evaluate the goodness of fit of the data to the models (20).
