Paragraph 8

Respiratory distress syndrome was more common in twin B (p < 0.001). Twin B ended up in a respirator (p < 0.001) more often but the amount of bronchopulmonary dysplasia or hypoxic ischemic encephalopathy diagnoses did not differ between twin A and B. Twin B also received more antibiotics than twin A (p = 0.002) and was more often admitted to NICU (p < 0.001) (Fig. 3) even though both the admittance rate to NICU and antibiotic use have risen markedly during the years for both twins (p < 0.001 for both). Sepsis diagnoses have, however, remained stable. Phototherapy was needed equally for both twins, but the amount of twin B at home by the age of seven days was significantly lower than twin A (p = 0.006).


Paragraph 5, sentence 3

The short-term morbidity in particular seems to be higher for twin B with possible consequences on early interaction.
