Should treatment recommendations for lipid lowering drugs be based on absolute coronary risk or risk reduction?

A risk reduction formula in this article by S Ramachandran and colleagues (11 March, pp 677-9) contained an error. The final sentence of the second paragraph should read: “The reduction in risk was calculated as the absolute five year risk × age factor (the age factor = (0.02357(a)²−3.179(a)+165.3)÷100, where a = the patient's age). The formula is calculated from reference 2.”
