Both groups consisted of 161 women with single pregnancies and 16 with twin pregnancies. Of the 188 LBW-children, 14% were twins. Of the single infants, 42% were appropriate for gestational age (AGA), i.e. within the 10th to 90th percentile according to Swedish curves for intrauterine growth, and 58% small for gestational age (SGA). The commonest causes of low birthweight (LBW) in the AGA-group were bleeding (34%) and premature rupture of the membranes (28%). In the SGA-group toxaemia was found in 15%, but in 50% of the SGA-group no cause of LBW was demonstrable. In this latter group the average placental weight was low. The mortality was noted and 89% of the living children were examined neurologically at 5 years of age. The prognosis of the child depended on the duration of pregnancy. Bleeding during pregnancy was a prognostically unfavourable sign, but even serious bleeding complications did not exclude a normal development of the child. The prognosis was best for those infants in whom no cause of LBW was demonstrable.","tracks":[{"project":"performance-test","denotations":[{"id":"PD-UBERON-AE-B_T1","span":{"begin":820,"end":829},"obj":"http://purl.obolibrary.org/obo/UBERON_0001987"}],"attributes":[{"subj":"PD-UBERON-AE-B_T1","pred":"source","obj":"performance-test"}]},{"project":"sentences","denotations":[{"id":"TextSentencer_T1","span":{"begin":0,"end":75},"obj":"Sentence"},{"id":"TextSentencer_T2","span":{"begin":76,"end":216},"obj":"Sentence"},{"id":"TextSentencer_T3","span":{"begin":217,"end":305},"obj":"Sentence"},{"id":"TextSentencer_T4","span":{"begin":306,"end":346},"obj":"Sentence"},{"id":"TextSentencer_T5","span":{"begin":347,"end":551},"obj":"Sentence"},{"id":"TextSentencer_T6","span":{"begin":552,"end":680},"obj":"Sentence"},{"id":"TextSentencer_T7","span":{"begin":681,"end":786},"obj":"Sentence"},{"id":"TextSentencer_T8","span":{"begin":787,"end":845},"obj":"Sentence"},{"id":"TextSentencer_T9","span":{"begin":846,"end":948},"obj":"Sentence"},{"id":"TextSentencer_T10","span":{"begin":949,"end":1014},"obj":"Sentence"},{"id":"TextSentencer_T11","span":{"begin":1015,"end":1171},"obj":"Sentence"},{"id":"TextSentencer_T12","span":{"begin":1172,"end":1254},"obj":"Sentence"},{"id":"T1","span":{"begin":0,"end":75},"obj":"Sentence"},{"id":"T2","span":{"begin":76,"end":216},"obj":"Sentence"},{"id":"T3","span":{"begin":217,"end":305},"obj":"Sentence"},{"id":"T4","span":{"begin":306,"end":346},"obj":"Sentence"},{"id":"T5","span":{"begin":347,"end":551},"obj":"Sentence"},{"id":"T6","span":{"begin":552,"end":680},"obj":"Sentence"},{"id":"T7","span":{"begin":681,"end":786},"obj":"Sentence"},{"id":"T8","span":{"begin":787,"end":845},"obj":"Sentence"},{"id":"T9","span":{"begin":846,"end":948},"obj":"Sentence"},{"id":"T10","span":{"begin":949,"end":1014},"obj":"Sentence"},{"id":"T11","span":{"begin":1015,"end":1171},"obj":"Sentence"},{"id":"T12","span":{"begin":1172,"end":1254},"obj":"Sentence"}],"namespaces":[{"prefix":"_base","uri":"http://pubannotation.org/ontology/tao.owl#"}],"attributes":[{"subj":"TextSentencer_T1","pred":"source","obj":"sentences"},{"subj":"TextSentencer_T2","pred":"source","obj":"sentences"},{"subj":"TextSentencer_T3","pred":"source","obj":"sentences"},{"subj":"TextSentencer_T4","pred":"source","obj":"sentences"},{"subj":"TextSentencer_T5","pred":"source","obj":"sentences"},{"subj":"TextSentencer_T6","pred":"source","obj":"sentences"},{"subj":"TextSentencer_T7","pred":"source","obj":"sentences"},{"subj":"TextSentencer_T8","pred":"source","obj":"sentences"},{"subj":"TextSentencer_T9","pred":"source","obj":"sentences"},{"subj":"TextSentencer_T10","pred":"source","obj":"sentences"},{"subj":"TextSentencer_T11","pred":"source","obj":"sentences"},{"subj":"TextSentencer_T12","pred":"source","obj":"sentences"},{"subj":"T1","pred":"source","obj":"sentences"},{"subj":"T2","pred":"source","obj":"sentences"},{"subj":"T3","pred":"source","obj":"sentences"},{"subj":"T4","pred":"source","obj":"sentences"},{"subj":"T5","pred":"source","obj":"sentences"},{"subj":"T6","pred":"source","obj":"sentences"},{"subj":"T7","pred":"source","obj":"sentences"},{"subj":"T8","pred":"source","obj":"sentences"},{"subj":"T9","pred":"source","obj":"sentences"},{"subj":"T10","pred":"source","obj":"sentences"},{"subj":"T11","pred":"source","obj":"sentences"},{"subj":"T12","pred":"source","obj":"sentences"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"performance-test","color":"#93d0ec","default":true},{"id":"sentences","color":"#eaec93"}]}]}}
