Comparison of Prehospital Versus Arrival Glasgow Coma Scale Scores Among Trauma Patients: A Retrospective Analysis.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionThe Glasgow Coma Scale (GCS) is a valuable tool that has long been used to help identify critically ill trauma patients in the prehospital setting. A discrepancy was observed by emergency medicine staff in prehospital GCS (pGCS) versus arrival GCS (aGCS). This observed discrepancy in GCS has important implications in the proper triage of trauma patients, including the appropriate level of activation, resource utilization, and cost. STUDY
objectiveThe aim of the study was to determine the level of agreement between pGCS and aGCS among trauma patients, determine the effect of alcohol intoxication on GCS agreement, analyze for differences in GCS among methods of transport, and limit confounding variables in the patient population.
methodsA single-center retrospective cohort of 2,531 trauma patients aged 14 and older who presented as level 1 and level 2 trauma alerts was included. To determine agreement, component, total, and categorical GCS scores were compared using weighted Cohen's kappa. In addition, the effect on agreement among acutely intoxicated trauma patients was assessed. Finally, absolute differences in mean scores stratified by method of transport were also evaluated.
resultsThe study included 2,531 patients. Overall agreement between pGCS and aGCS was moderate (kappa 0.54) with substantial agreement (kappa 0.67) when categorized by severity. Alcohol intoxication decreased agreement to moderate agreement (kappa 0.57). pGCS tended to be lower than aGCS for ground Emergency Medical Services (EMS) (-0.45) and higher for air EMS (0.7).
conclusionGCS agreement between prehospital and emergency department (ED) providers is similar, with variation among methods of transport and patients who are acutely intoxicated; however, this difference may not be clinically significant.
