Description of the study population, study design and research questions (Q1–Q4): The study includes only study participants with Lp(a) measurements available at baseline. For Q1 test results, all participants were included who became available from 16 March 2020 until 1 February 2021. For Q2–Q4, outcome data were available from 16 March 2020 to 30 November 2020. Therefore, the number of tested individuals is lower for this part of the study, and the number of the background population is therefore higher as for Q1.
