There are two different errors in “Postpartum Sterilization With the Titanium Clip: A Systematic Review” by M. I. Rodriguez, A. B. Edelman, and N. Kapp (Obstet Gynecol 2011;118: 143–7). Readers may refer to an accompanying Letter to the Editor and Reply in this issue on p. 958.
- 1. The failure rate of a sterilization method was incorrectly reported as 0.04, when it should have been reported as 0.4. The authors regret these errors.
- In the Tabulation, Integration, and Results paragraph in the Abstract, the last sentence should read, “This trial found a significantly increased risk of pregnancy at 24 months with clip sterilization postpartum (cumulative rate 1.7 compared with 0.4, P=.04) compared with postpartum partial salpingectomy.”
- In the first line of the Results column in Table 1, the second paragraph should read, “Pomeroy: 2 pregnancies/414 women at 24 mo; cumulative pregnancy rate 0.4; P=.04.”
- In the first column at the top of page 146, the last sentence in the first paragraph should read, “This study showed a significantly increased risk of pregnancy at 24 months with clip sterilization postpartum (1.7 compared with 0.4, P=.04).”
- 2. References 19–24 were omitted from the reference list. The missing references are printed below. This error occurred during production.

In “Predictors of Cesarean Delivery for Periviable Neonates” by B. Tucker Edmonds, C. Fager, S. Srinivas, and S. Lorch (Obstet Gynecol 2011; 118:49–56), weeks of gestation was sometimes incorrectly expressed as a decimal. These errors occurred during production.
- The Abstract, Results section should read, “This was a retrospective cohort study of state-level maternal and neonatal hospital discharge data linked to vital statistics data for deliveries occurring between 23 0/7 and 24 6/7 weeks of gestation in California, Missouri, and Pennsylvania from 1995 to 2005 (N=8,290).”
- The beginning of the second paragraph of the Materials and Methods section should read, “Live singleton births and “in-hospital” fetal deaths occurring between 23 0/7 and 24 6/7 weeks of reported gestational age were included in the analysis. Gestational age variables were missing in approximately 8% of the data. To use all available data, we also included neonates with birth weights that reasonably could have occurred at a gestational age between 23 0/7 and 24 6/7 weeks, assessed using available fetal growth curves.18”
- The last two sentences of the Results section should read, “Last, women presenting at a gestational age between 24 0/7 and 24 6/7 weeks had more than twice the odds of cesarean delivery compared with women presenting between 23 0/7 and 23 6/7 weeks of gestation (OR 2.14, 95% CI 1.92–2.39, risk difference 0.12), which translates to an additional cesarean delivery for every eight neonates born between 24 0/7 and 24 6/7 weeks. Neither adjusting for delivery hospital nor stratifying the analysis by state changed these findings.”
The first sentence is incorrect in the Reply to the Letter to the Editor titled, “Using a Simplified Bishop Score to Predict Vaginal Delivery” by S. K. Laughon, J. Zhang, and U. M. Reddy (Obstet Gynecol 2011; 360). The first two sentences should read, “We appreciate the comments of Drs. Tajik, Bossuyt, and Mol. Bishop demonstrated that a pelvic score was associated with time to spontaneous labor.1” The Editorial Office regrets this error.
