CORRECTION Open AccessCorrection to: Perinatal outcomes in Finnishtwins: a retrospective studyAnnu-Riikka Susanna Rissanen1*, Riina Maria Jernman2, Mika Gissler3,4, Irmeli Katriina Nupponen5 andMika Erkki Nuutila2Correction to: BMC Pregnancy Childbirth 2, 20 (2020)https://doi.org/10.1186/s12884-019-2670-3Following publication of the original article [1], theauthors identified some errors in the Results and Discussionsections.The Results and Discussion sections have been replacedwith the updated version and the changes have beenhighlighted in bold typeface.ResultsParagraph 8Respiratory distress syndrome was more common in twinB (p < 0.001). Twin B ended up in a respirator (p < 0.001)more often but the amount of bronchopulmonary dysplasiaor hypoxic ischemic encephalopathy diagnoses did not differbetween twin A and B. Twin B also received more antibi-otics than twin A (p = 0.002) and was more often admit-ted to NICU (p < 0.001) (Fig. 3) even though both theadmittance rate to NICU and antibiotic use have risenmarkedly during the years for both twins (p < 0.001 forboth). Sepsis diagnoses have, however, remained stable.Phototherapy was needed equally for both twins, but theamount of twin B at home by the age of seven days wassignificantly lower than twin A (p = 0.006).DiscussionParagraph 5, sentence 3The short-term morbidity in particular seems to behigher for twin B with possible consequences on earlyinteraction.Author details1Department of Obstetrics and Gynecology, University of Helsinki andWelfare District of Päijät-Häme, Keskussairaalankatu 7, 15850 Lahti, Finland.2Obstetrics and Gynecology, University of Helsinki and Helsinki UniversityHospital, Haartmaninkatu 2, PL 140, 00029 HUS Helsinki, Finland. 3FinnishInstitute for Health and Welfare, Mannerheimintie 166, PL 30, 00271 Helsinki,Finland. 4Karolinska Institute, Stockholm, Sweden. 5Children’s Hospital,University of Helsinki and Helsinki University Hospital, Stenbäckinkatu 9,PL347, 00029 HUS Helsinki, Finland.Reference1.
