A study was conducted to determine the effect of the addition of a particular supplement to a well-known LDL lowering cholesterol drug. 5000 randomly selected patients were studied on this combination of drugs over a one-year period. An increased reduction of 5 mg/dL of LDL cholesterol was achieved with the combination of drugs relative to the well-known drug alone. The reduction resulted in a P -value of 0.001.
