Schneider CA, Ferrannini E, DeFronzo R, Schernthaner G, Yates J, and Erdmann E: Effect of Pioglitazone on Cardiovascular Outcome in Diabetes and Chronic Kidney Disease. J Am Soc Nephrol 19: 182–187, 2008.

Please note the following corrections in the above article published in the January 2008 issue of the Journal of the American Society of Nephrology. In this article, the data errors were caused by (1) description of events at average follow-up rather than overall and (2) a transcription error. Also, the correct version of the Modification of Diet in Renal Disease (MDRD) formula is now described in Concise Methods. These errors do not alter the data interpretation or affect the study conclusions.

The following are corrections to the manuscript.

• In the third paragraph of Results (p 184), the sentence “All-cause mortality rates were 7.7% (n = 21) in the pioglitazone group and 13.6% (n = 44) in the placebo group (HR, 0.75; 95% CI, 0.55 to 1.03)” should have read “All-cause mortality rates were 8.0% (n = 22) in the pioglitazone group and 13.9% (n = 45) in the placebo group (HR, 0.55; 95% CI, 0.33 to 0.92).”

• In the fourth paragraph of Results (p 184), the sentence “The proportion of patients who had a GFR≥60 ml/min per 1.73 m² and subsequently died from any cause was also similar between groups (n = 137 [6.0%] with pioglitazone versus n = 130 [5.7%] with placebo; HR, 1.09; 95% CI, 0.87 to 1.38)” should have read “The proportion of patients who had a GFR≥60 ml/min per 1.73 m² and subsequently died from any cause was also similar between groups (n = 148 [6.5%] with pioglitazone versus n = 134 [5.9%] with placebo; HR, 1.09; 95% CI, 0.87 to 1.38).”

• In the first paragraph of Procedures in Concise Methods (p 186), the sentence “GFR was estimated using the simplified MDRD formula: 186.2 × serum creatinine in mg/dl^−1.154 × age in yr^−0.203 × 1.212 if black × 0.742 if female” should have read “GFR was estimated using the simplified MDRD formula: 186 × serum creatinine in milligrams per deciliter^−1.154 × age in years^−0.203 × 0.742 for women.”
