Key Points

This study aims to explore the relationship between the GCS-P score and brain CT findings in head trauma patients.
Retrospective study of 300 adult patients with acute head injuries over 3 months
Standardized neurological evaluation, including GCS and pupillary assessments, followed by noncontrast CT imaging
Spearman's rank correlation analysis between GCS-P scores and CT injury severity
Strong negative correlation between GCS-P score and CT severity (ρ = -0.682, P < 0.001)
Patients with severe CT findings had significantly lower GCS-P scores (5.9 ± 2.4) than those with mild (12.4 ± 2.1) or normal imaging (14.0 ± 1.6) (P < 0.001)
23.3% of CT scans revealed severe injury.

We only have this paper's title and publication details.
