Erratum to: The use of balloons for uterine cervical ripening is associated with an increased risk of umbilical cord prolapse: population based questionnaire survey in Japan

The original article was published in BMC Pregnancy and Childbirth 2015 15:4

Erratum

After publication of the original article [1], it came to the authors’ attention that a few values in Table 2 were added incorrectly. The correct values are as follows: for total cases ‘disk shape balloon’ and ‘ball type balloon’ the incidence observed was 0.037 % (14/38348) and 0.060 % (28/46640), respectively. All other values within Table 2 are correct.
