Am Fam Physician. 2001;64(1):36-38

The article “Alternative Therapies: Part II. Congestive Heart Failure and Hypercholesterolemia” (September 15, 2000, page 1325) contained an error in the second sentence of the first full paragraph in the right-hand column on page 1328. The correct sentence reads as follows: “This ‘red rice yeast product’ has been used for centuries in China and contains starch, protein, fiber and at least eight statin compounds, which function as 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase inhibitors.” The abbreviation was also incorrectly expanded in Table 1. The corrected table is reprinted above.
