Corrigendum to "Maternal and Perinatal Outcome in Women with Systemic Lupus Erythematosus: A Retrospective Bicenter Cohort Study".

[This corrects the article DOI: 10.1155/2017/8245879.].

In the article titled “Maternal and Perinatal Outcome in Women with Systemic Lupus Erythematosus: A Retrospective Bicenter Cohort Study” [1], the authors identified some discrepancies in the data following its publication.

There are very small changes in incidence of HELLP syndrome (N = 5 instead of N = 7), preeclampsia (N = 22 instead of 24), and mild hypertensive disorder (N = 19 instead of 21), which showed no significant difference in the preeclampsia group. The incidence of preeclampsia <34 weeks, eclampsia, and HELLP syndrome were too low to conduct the generalized estimating equations (GEE) analysis; therefore, a new p value cannot be produced. Due to the very small differences, we believe that our conclusions are not changed. As already described on page 6 of the article: “In our cohort, we only found an association with APS and HELLP. However, considering the low numbers of HELLP in the paper by Moroni et al. (2 out of 71 pregnancies = 2.6%) and our study (7 out of 144 pregnancies = 4.9%), we do not venture to interpret these findings.”

The corrected Table 3 is shown below.

Maternal and perinatal pregnancy complications in all study pregnancies.

Maternal complications	N = 144	N = 117	N = 14	N = 13
Mild HD	19/144 (13.2)	16/117 (13.7)	1/14 (7.1)	2/13 (15.4)	ns

Additionally, in Section 3.3.2, the sentence “Of all preterm births (<37 weeks), 44.2% occurred spontaneously, and in the others, labour was induced. Main indications for preterm induction of labour (<37 weeks) were HD (54.1%) and IUFD (12.5%).” should be corrected to “Of all preterm births (<37 weeks), 61.9% occurred spontaneously. Main indications for preterm induction of labor (<37 weeks) were HD (30.8%) and IUGR (23.1%). IUFD as reason for preterm induction of labor occurred once (7.7%).”

Also, the email address of the corresponding author should be changed to “s.kroese@hagaziekenhuis.nl.”

The authors confirm that this does not affect the results and conclusions of the article, and the editorial board agrees to the publication of a corrigendum.
