Designated and non-designated trauma centers and trauma patients: a retrospective analysis of non-fatal trauma discharges in Georgia, 2021.
Article in Injury epidemiology, 2026. 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
backgroundDirecting trauma patients to Designated Trauma Centers (DTCs) for treatment of trauma injury is vital to ensure patients’ access to quality trauma care. We study injury severity and distance to DTCs as major factors associated with care and discharge of trauma patients.
methodsWe conducted a retrospective cross-sectional study using 2021 de-identified non-fatal hospital discharge data from Georgia, identifying 225,389 unique adult trauma patients with single discharge records. The outcome was the discharging hospital’s trauma designation. Predictors included whether the nearest hospital was DTC, road network distance to the nearest DTC, and the International Classification of Diseases-based Injury Severity Score (ICISS). Logistic regression with backward stepwise selection identified predictors of DTC vs. Non-designated Trauma Center (NTC) discharge, adjusting for sociodemographic, health, and injury characteristics.
resultsPatients discharged from DTCs (N = 107,743) had more severe injuries (ICISS ≤ 0.85: 1.6% vs. 0.3%) compared to NTC discharges (N = 117,646) and lived in zipcodes where the nearest hospital was a DTC (41.3% vs. 11.5%). The predicted probability of discharge from DTC exceeded 0.77 irrespective of travel time when the nearest hospital was a DTC. However, when the nearest hospital was not DTC, the probability of discharge from DTC decreased as travel time to the nearest DTC increased, i.e., from 0.735 (95%CI: 0.689, 0.782) for < 12.5 min to 0.16 (95%CI: 0.128, 0.192) for > 38.8 min. This decrease was more pronounced for less-severe patients.
conclusionsA lower probability of discharge from a DTC corresponds to a higher probability of discharge from an NTC. When the nearest hospital was not DTC, the likelihood of NTC discharge increased with longer travel times to the nearest DTC. In Georgia, NTCs play a crucial role in the statewide trauma system by providing care to seriously injured patients when DTCs are geographically distant. These findings underscore the importance of NTCs in ensuring timely and accessible trauma care, particularly in regions where DTCs are not readily accessible.
