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

backgroundThere continues to be an ongoing debate regarding the utility of head CT scans in patients with a normal Glasgow Coma Scale (GCS) after minor head injury. The objective of this study is to determine patient and injury characteristics that predict a positive head CT scan or need for a neurosurgical procedure (NSP) among patients with blunt head injury and a normal GCS. MATERIALS AND

methodsRetrospective analysis of adult patients in the National Trauma Data Bank who presented to the ED with a history of blunt head injury and a normal GCS of 15. The primary outcomes were a positive head CT scan or a NSP. Multivariate logistic regression controlling for patient and injury characteristics was used to determine predictors of each outcome.

resultsOut of a total of 83,566 patients, 24,414 (29.2%) had a positive head CT scan and 3476 (4.2%) underwent a NSP. Older patients and patients with a history of fall (compared with a motor vehicle crash) were more likely to have a positive finding on a head CT scan. Male patients, African-Americans (compared with Caucasians), and those who presented with a fall were more likely to have a NSP.

conclusionsOlder age, male gender, ethnicity, and mechanism of injury are significant predictors of a positive finding on head CT scans and the need for neurosurgical procedures. This study highlights patient and injury-specific characteristics that may help in identifying patients with supposedly minor head injury who will benefit from a head CT scan.
