* A Nov. 3 article on the proposed merger of Anthem and WellPoint Health Networks (p. 6) incorrectly stated that WellChoice, New York, planned to remain independent and had adopted provisions to prevent a takeover. The for-profit parent of Empire Blue Cross and Blue Shield remains open to acquisition and merger opportunities. The original statement should have been attributed to Shellie Stoddard, senior healthcare analyst with Standard & Poor's.
* The Dec. 1 Outliers column (p. 36) incorrectly stated the Web address for the online organization PatchWorx. The correct address is patchworx.org.
