Dear Editor
Due to an oversight a reference was inadvertently missed out from the article as follows:
A large Swedish study that compared singleton live births in women with gastric bypass and matched controls found no cases of neural tube defects in the surgery group and 20 cases (0.07%) among controls (Neovius et al., 2019).
