Association of the HDL-C/apoA-1 ratio with the serum EPA level. The patients were divided into quartiles of the EPA concentration. The ranges according to the quartile of EPA were follows: 6.2–40.0 μg/mL (quartile 1: n = 160), 40.1–62.8 μg/mL (quartile 2: n = 160), 63.0–92.2 μg/mL (quartile 3: n = 160), and 92.4–373.5 μg/mL (quartile 4: n = 160). The serum HDL-C level increased significantly as the serum EPA quartile increased, while the serum apoA-1 level also increased significantly as the serum EPA quartile increased. Accordingly, no significant change in the serum HDL-C/apoA-1 ratio is found as the serum EPA quartile increased.
