The story "FDA Panel Urges Review of CV Risks of Diabetes Drugs" (July 15, p. 1) should have stated that people with type 2 diabetes have a two-to fourfold greater risk of cardiovascular mortality, compared with patients without diabetes.

"Six-Gene Cluster Stratifies Need for Colonoscopy" (July 1, p. 45) should have said that the six-gene panel was 70.3% accurate, including 127 true-positive, 110 true-negative, 61 false-positive, and 39 false-negative results.
