Ballard TLP, Clapper JA, Specker BL, Binkley TL, Vukovich MD. Effect of protein supplementation during a 6-mo strength and conditioning program on insulin-like growth factor I and markers of bone turnover in young adults. Am J Clin Nutr 2005;81:1442-8.

Table 1 (page 1444) contains an error, which the authors recognized when another manuscript from the same study was in review. The analysis of the calcium data included a supplement amount of only 1 serving, but it should have included an amount of 2 servings; therefore, the data should reflect an additional 500 mg Ca. The error occurred only for calcium. The authors reanalyzed the data with the correct amount of calcium, and a revised Table 1 is printed here. The interpretation of the data did not change.
