A detailed description of blood collection and laboratory measurements has been previously published [10 (link)]. Routine laboratory measurements were performed in fresh serum (basic lipid profile [TC, TG, LDL-C], AST, ALT, CK). The remaining serum was aliquoted and stored at −80°C until assayed for hs-CRP, apoB, Lp(a). All measurements (except for CRP) were performed using the Horiba ABX Pentra 400 analyzer (Horiba ABX, Montpellier, France). LDL-C was measured directly. CRP was measured using the Alinity c analyzer (Abbott Laboratories, Chicago, IL, USA) with the Alinity c CRP Vario High Sensitivity assay for the quantitative, immunoturbidimetric determination of CRP with a limit of detection of 0.4 mg/L. Laboratory measurements were performed at the Department of Laboratory Medicine, Nicolaus Copernicus University, Collegium Medicum, Bydgoszcz, Poland.
