Erratum to: Maternal Mortality in Texas

The authors have brought to the publisher's attention that there were some errors in the “Methodologic Issues” section and in [Table 1] in the above article in the American Journal of Perinatology, published online on November 9, 2016 (DOI: 10.1055/s-0036-1595809).

In “Methodologic Issues” section, the fourth paragraph should read as follows:

Method 3 uses counts of live births and maternal deaths among Texas residents, obtained from the Center for Health Statistics at TDSHS, that occur within 42 days following the end of pregnancy, if one or more of the same ICD-10 codes used in Methods 1 and 2 are present on the death certificate. Again, maternal death counts for each year differed slightly from those obtained using NCHS death data, due to the potential reasons described earlier for Method 1. Method 3 compares an actual MMR for 2011 (26.5 maternal deaths per 100,000 live births) with an actual MMR for 2010 (18.7 maternal deaths per 100,000 live births), yielding a 42% increase in MMR within 42 days following the end of pregnancy among Texas residents.

The correct [Table 1] appears as follows:
