In the Research Letter titled “Association Between Mode of Delivery Among Pregnant Women With COVID-19 and Maternal and Neonatal Outcomes in Spain,”1 published online in JAMA on June 8, 2020, there were errors in data and erroneously reported statistical significance for the outcome of admission to the neonatal intensive care unit (NICU). In the third paragraph of the Results, the second sentence was revised to read “After adjustment for confounding factors, cesarean birth was not significantly associated with an increased risk of NICU admission (adjusted odds ratio, 1.2; 95% CI, 0.3-4.5; P = .76).” In the second paragraph of the Discussion, the sentence “Cesarean delivery was also associated with an increased risk of NICU admission” was deleted. The final paragraph of the Discussion was revised to read “Limitations include a lack of sufficient information on newborns to determine vertical transmission. The lack of association between cesarean delivery and risk of NICU admission may have been related to the lack of statistical power. Also, the 95% CIs around the odds ratios for cesarean birth and clinical deterioration were wide and the estimates fragile.” In Table 2, for the row labeled “Neonatal intensive care unit admission,” the odds ratio and 95% CI for asymptomatic/mild COVID-19 symptoms were revised to “1.7 (0.5-5.8)” and the adjusted odds ratio and 95% CI were revised to “1.2 (0.3-4.5).”2 This article was corrected online.
