In the article, “Adiponectin and Coronary Heart Disease: A Prospective Study and Meta-Analysis” by Sattar et al that published in the August 15, 2006, issue (Circulation. 2006;114:623-629), the assay method attributed to the study of Zoccali et al in Table 4 was incorrectly stated as the assay by Linco; it was an in-house ELISA and done on frozen rather than fresh samples. In addition, with respect to the study of Wolk et al in the same table, frozen rather than fresh blood samples were used.

The authors regret these errors.
