Correction to: Journal of Perinatology; https://doi.org/10.1038/s41372-018-0095-x; published online 08 May 2018

The previously published version of this Article contained an error in Fig. 1 where the “HR low” and “HR high” labels were swapped.

Furthermore, in Table 1 of this Article, the fifth row in the centre column contained a typographical error where the study population birth weight incorrectly read “2050 (1 450–2 650)”, rather than “2050 (1450–2650)”.

These errors have now been corrected in both the PDF and HTML versions of the Article.
