The investigators will carry out multi-center and large sample research based on the Chinese population, screen the optimal diagnostic and prognosis recognition biomarkers and analyze the diagnostic critical cutoff values in patients with mild to moderate traumatic brain injury, so as to provide a substantial basis for clinical diagnosis and prognosis recognition.
Traumatic brain injury (TBI) is a complex disorder that comprises a spectrum of intracranial pathologies, many of which present diagnostic challenges. Detection of intracranial injuries after TBI relies on head CT, which is overused and resource intensive. Prior studies have shown the potential for blood-based brain injury biomarkers to predict the absence of intracranial injury after TBI and aid in reducing unnecessary head CT use. Furthermore, plasma biomarker concentrations in the acute phase after TBI identified patients with a suspected TBI and normal head CT who had detectable pathology on MRI. However, most of the current studies are based on the European and American population, and whether the research results are applicable to the Chinese population remains to be studied. Therefore, the investigators will carry out multi-center and large sample research based on the Chinese population, screen the optimal diagnostic and prognosis recognition biomarkers and analyze the diagnostic critical cutoff values, so as to provide a substantial basis for clinical diagnosis and prognosis recognition.

Time frame: post-traumatic for 12 months
Number of participants with positive head CT scan
CT-positive was defined as the presence of one or more of the following injuries: acute epidural haematoma, acute subdural haematoma, indeterminate extraaxial haemorrhage, intraventricular haemorrhage, parenchymal haematoma, petechial haemorrhagic or bland sheer injury, subarachnoid haemorrhage, brain oedema, brain herniation, non-haemorrhagic contusion, ventricular compression, ventricular trapping, cranial fractures, depressed skull fractures, facial fractures, scalp injury, or skull base fractures.
Time frame: baseline (early injury)
Number of participants with MRI abnormalities
MRI abnormalities were quantified according to common data elements standards and definitions by three board-certified neuroradiologists masked to the identity and clinical history of the patient. MRI scans were read as positive if there was evidence of acute intracranial pathology consistent with TBI (eg, contusion, traumatic axonal injury, diffuse axonal injury).
