In "The Risk of Pregnancy After Vasectomy" by D. J. Jamieson, MD, MPH, C. Costello, MPH, J. Trussell, PhD, S. D. Hillis, PhD, P. A. Marchbanks, PhD, and H. B. Peterson, MD, for the U.S. Collaborative Review of Sterilization Working Group (Obstet Gynecol 2004;103:848–50), a date from a data collection form was entered incorrectly, which resulted in a mistake in the point estimates and 95% confidence intervals for the 1-year failure rates. Although the overall conclusions do not change, the point estimate for the 1-year failure rate does. The incorrectly reported point estimate is 9.4 (95% CI 1.2, 17.5) and the correct point estimate is 7.4 (95% CI 0.2, 14.6). The 95% confidence intervals for the incorrect and correct estimates overlap and, thus, the incorrect and correct point estimates are within the same range. This error in data entry does not affect the 5-year failure rates, upon which we base our conclusions.
The article should be corrected as follows:
- Abstract (Page 484, lines 13–14):Current: "...per 1,000 procedures (95% confidence interval) was 9.4 (1.2, 17.5) 1 year after vasectomy..."Corrected: "...per 1,000 procedures (95% confidence interval) was 7.4 (0.2, 14.6) 1 year after vasectomy..."
- Results (Page 849, second column, line 10):Current: "...(95% confidence intervals) was 9.4 (1.2, 17.5)..."Corrected: "...(95% confidence intervals) was 7.4 (0.2, 14.6)..."
- Results (Page 849, second column, line 17):Current: "...1,000 procedures would be 11.2 (2.3, 20.1) at 1 year after..."Corrected: "...1,000 procedures would be 9.2 (1.2, 17.3) at 1 year after..."
