Erratum.
Two statements in the article "Heart panel's conclusions questioned" by Gina Kolata (Research News, 4 Jan., p. 40) were not accurate. The first, in the third paragraph on page 40, should have read, "But these trials failed to show that cholesterol-lowering saves lives," instead of, "But these trials failed to show that cholesterol-lowering prevents deaths from heart disease." A second statement, in the ninth paragraph on page 41, should have read, "The incidences of angina, bypass surgery, and abnormal exercise electrocardiograms all came down in the cholestyramine group. All but bypass surgery were statistically significant."
