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

aimThe primary aim was to investigate the incidence, birth characteristics, and timing of diagnosis of cephalhaematoma (CH). The secondary aim was to explore associations between CH and complications during the neonatal period and infancy.

methodsThis is a nationwide population-based register study of infants (< 12 months) born in Sweden from 1997 to 2018. Information was retrieved from health registers of the Swedish National Board of Health and Welfare. Cases were infants with a diagnosis of birth-related CH.

resultsThe study comprises 2930 infants with CH. The incidence was 2.2 per 1000 births and increased during the study period. Most CH cases had a spontaneous vaginal delivery. Risk factors were ventouse, born preterm, large-for-gestational age, and occiput posterior presentation. Two-thirds were diagnosed before 7 days of life. A delayed diagnosis during later infancy became more common from the year 2000. Newborn infants had an increased risk of jaundice (10%). CH was associated with hypoxic encephalopathy (2.5%), convulsions (3.5%), skull fractures (0.6%), intraventricular haemorrhage (0.2%), subdural haemorrhage (0.5%) and stroke (0.2%).

conclusionA substantial number of CH cases had a delayed diagnosis. A minority displayed symptoms of serious head trauma. CH was associated with intracranial haemorrhage.
