The International Journal of Gynecology and Obstetrics regrets that, in the above article, an error appeared in the Results section of the Abstract; Instead of “lower estimated ovulation number,” “higher estimated ovulation number” should be written. The corrected sentence appears as follows: Shorter mean length of oral contraceptive pill use before trisomic pregnancy (P<0.001) and a higher estimated ovulation number (P=0.012) were identified among patients with pregnancies with fetal trisomies. The International Journal of Gynecology and Obstetrics would like to apologize for any inconvenience caused.
