Box-and-whisker plots of the %bias of the low-density lipoprotein-cholesterol (LDL-C) and high-density lipoprotein-cholesterol (HDL-C) homogeneous assays (HAs) in the non-diseased and diseased groups

The LDL-C and HDL-C concentrations of fresh blood samples were simultaneously measured using HAs and the reference measurement procedures (RMPs) of the Centers for Disease Control and Prevention (CDC), as described in the Methods. %bias is the percentage deviation of the HA value from the RMP value.
