2 Figure 1 Interindividual variation in MetS subjects in response to pitavastatin treatment (4 mg/d) over the time course from baseline (D0), to 6 days (D6), to 42 days (D42), and to 180 days (D180). (A) LDL-C (n = 12) and (B) fasting triglycerides (n = 11); data for 1 subject whose response presented as an outlier (>10-fold variation in SD value) were excluded. MetS, metabolic syndrome; LDL-C, low-density lipoprotein cholesterol. Journal of Clinical Lipidology  , e4DOI: ( /j.jacl ) Copyright © 2017 National Lipid Association Terms and Conditions

3 Figure 2 Time course of the impact of pitavastatin treatment (4 mg/d) in MetS subjects on total mass (TG, CE, FC, PL, and protein; expressed as mg/dL plasma) of individual lipoprotein subfractions isolated by density gradient ultracentrifugation. Subfractions are VLDL + IDL and LDL (LDL1 + LDL2 to LDL5) at baseline (D0), and 180 days (D180), and for HDL subfractions at baseline (D0), 6 days (D6), 42 days (D42), and 180 days (D180). The hydrated density limits of individual fractions were VLDL + IDL, d < 1.019 g/mL; LDL1 + LDL2, 1.019–1.029 g/mL; LDL3, 1.029–1.039 g/mL; LDL4, 1.039–1.050 g/mL; LDL5, 1.050–1.063 g/mL; HDL2b, 1.063–1.091 g/mL; HDL2a, 1.091–1.110 g/mL; HDL3a, 1.110–1.133 g/mL; HDL3b, 1.133–1.156 g/mL; and HDL3c, 1.156–1.179 g/mL. Inserts: % change between baseline and D180 in total mass of (1) VLDL + IDL and LDL subfractions and (2) HDL subfractions. ***P < .001, **.001 < P < .01, and *0.01 < P < .05 vs D0. VLDL, very low–density lipoproteins; IDL, intermediate–density lipoprotein; LDL, low-density lipoprotein; HDL, high-density lipoprotein; TG, triglyceride; CE, cholesteryl ester; FC, free cholesterol; PL, phospholipid.

The hydrated density limits of individual lipoprotein subfractions from the density gradient are as given in the legend in Figure 2. ***P < .001, **.001 < P < .01, and *0.01 < P < .05 vs D0.
