Plasma levels of biomarkers associated with vasodilation and neuroinflammation in pediatric patients with head trauma and their relationship with clinical characteristics of patients.

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
purposeTraumatic brain injury in children can lead to lifelong sequelae and disabilities. Identifying the mediators of the neuroinflammatory process resulting from head trauma is of great importance. We therefore explored the plasma levels of neurogenic inflammatory and vasodilator peptides in children with head trauma and their relationship with the clinical characteristics of the patients.
methodsForty head-traumatized and 26 healthy children aged 2 months-7 years old were prospectively enrolled in the study. Demographic characteristics of patients and controls were recorded. Glasgow coma score (GCS), cause of trauma, computed tomography (CT) results, blood pressure, and pulse rate were recorded. Plasma calcitonin gene-related peptide (CGRP), pituitary adenylate cyclase-activating polypeptide-38 (PACAP-38), vasoactive intestinal peptide (VIP), and substance P (SP) levels of patients and controls were measured by ELISA. Correlation and ROC analyses were carried out.
resultsThe mean GCS of the patients was 14.8 ± 0.4, which was in the mild traumatic brain injury (mTBI) category. Plasma levels of CGRP, PACAP-38, VIP, and SP in patients with head trauma were significantly higher than controls. All peptide levels were significantly higher in CT-positive patients than in CT-negative patients who had only head trauma. Only CGRP was higher in female patients than in the males. A positive correlation was found between CGRP, PACAP-38, and SP levels, as well as between PACAP-38 and VIP. ROC analysis detected that these peptides had a diagnostic value in mTBI.
conclusionEvaluation of pediatric patients with head trauma together with these neuropeptides may provide great benefits in deciding whether to perform radiography such as CT. However, due to the relatively low sensitivities in ROC analysis and small sample size, further studies are warranted before they may be used as a screening test to distinguish CT-positive from CT-negative patients.
