Figure 4. Change in PCSK9 concentrations (in percent from baseline) according to baseline PCSK9 concentrations and change in LDL cholesterol (in percent from baseline).

Subjects were divided approximately in tertiles: baseline PCSK9<40 ng/mL, 40 to <60 ng/mL, or ≥60 ng/mL; change in LDL cholesterol from baseline <30%, 30 to <50%, or ≥50%.
