Evaluation of diagnostic performance of PECARN clinical decision rule in children with minor head trauma presenting to the emergency department of a tertiary care center: an observational study.

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.
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
purposeMinor head trauma is one of the most common reasons for pediatric emergency department visits. Accurate identification of children at risk for clinically important traumatic brain injury (ciTBI) is essential to reduce unnecessary computed tomography (CT) imaging. This study evaluated the diagnostic performance of the PECARN (Pediatric Emergency Care Applied Research Network) clinical decision rule in children with minor head trauma presenting to a tertiary care hospital in South India.
methodsIn this observational study conducted between September 2022 and April 2024, 235 children aged <18 years presenting with head trauma and Glasgow Coma Scale scores of 14-15 were prospectively enrolled. Participants were stratified into age-specific PECARN risk categories. Diagnostic performance was assessed against ciTBI outcomes defined by clinical and radiological criteria.
resultsThe PECARN rule demonstrated strong diagnostic performance, with a sensitivity of 82.4%, specificity of 74.1%, and an area under the receiver operating characteristic curve of 0.90 (P=0.01). No cases requiring neurosurgical intervention were missed. Children aged ≥2 years had a higher incidence of ciTBI than those aged <2 years (13.4% vs. 1.8%, P=0.048). ciTBI was significantly associated with loss of consciousness, vomiting, severe headache, and signs of basilar skull fracture (all P<0.001).
conclusionsThe PECARN rule appears to be a reliable and safe tool for evaluating pediatric minor head trauma in Indian emergency settings. Its high sensitivity and negative predictive value support its use in reducing unnecessary CT imaging while accurately identifying children at risk for ciTBI.
