1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundDeficiency of vitamin K predisposes to early, classic, or late vitamin K deficiency bleeding (VKDB), of which late VKDB may be associated with serious and life-threatening intracranial bleeding. Late VKDB is characterized with intracranial bleeding in infants aged 2-24 weeks due to severe vitamin K deficiency, occurring primarily in exclusively breast-fed infants. Late VKDB is still an important cause of mortality and morbidity in developing countries. MATERIALS AND

methodsWe presented 120 cases of late VKDB, which were evaluated at Erciyes University Medical Faculty Hospital between June 1990 and June 2006.

resultsSigns and symptoms of the patients were bulging fontanels (70%); irritabilities (50%); convulsions (49%); bleeding and ecchymosis (47%); feeding intolerance, poor sucking, and vomiting (46%); diarrhea (34%); jaundice (11%); and pallor (9%), and among these infants, 21% received medication before the diagnosis (10%, antibiotics; 3%, simethicone; 4%, paracetamol; and 4%, phenobarbital). Intracranial hemorrhage in 88 (73%) patients has been observed. The hemorrhage was subdural in 34 (28%) cases, intracerebral in 28 (23%), subarachnoid in 17 (14%), intraventricular in 9 (8%), intracerebral and subdural in 12 (10%), subdural and subarachnoid in 6 (5%), and combination of intracerebral, subdural, and intraventricular in 14 (12%), and the mortality rate was 31%.

conclusionAlthough late VKDB leads to significant morbidity and mortality, it can be avoided by providing vitamin K prophylaxis to all newborns. Administration of vitamin K (1 mg) at birth can prevent intracranial bleeding and other hemorrhagic manifestations.
