Elevated triglyceride/high-density lipoprotein cholesterol (TG/HDL) ratio means having a value of triglyceride (mg/dL) divided by HDL-cholesterol (mg/dL) that is 3.75 or higher in men or 3.0 or higher in women. All others are considered “normal.” Note that only 777 patients had TG/HDL ratio at baseline that was actually elevated. An additional 22 patients are included in this group because they were treated for dyslipidemia (fibrate, niacin, or omega 3 polyunsaturates).
