Comparison of Risk Assessment Tools' Prediction of Outcomes for Penetrating Trauma.
Observational study in The Journal of surgical research, 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 Trauma and Injury Severity Score (TRISS) uses anatomic and/or physiologic variables to predict mortality; however, Injury Severity Score is less reliable for penetrating trauma. National Surgical Quality Improvement Program Surgical Risk Calculator (NSQIP-SRC) and American Society of Anesthesiologists Physical Status (ASA-PS) include functional status and comorbidities. This study evaluates the accuracy of these tools in predicting mortality, length of stay (LOS), and complications for operative penetrating trauma.
methodsAdult penetrating trauma patients (≥18 y) who underwent surgery within 24 h of admission were included in this subgroup analysis of a prospective observational study at four trauma centers. The following three scoring models were compared: NSQIP-SRC, TRISS, and ASA-PS. Brier scores and area under the receiver-operating characteristic curve were used to compare mortality prediction. LOS prediction was assessed with linear regression and complications were evaluated with negative binomial regression. Likelihood ratio (LR) test was used to assess model fit.
resultsOf 329 penetrating trauma patients, 13 (3.9%) died. The median LOS was 4 d (interquartile range 2-9), and median number of complications was zero (interquartile range 0-1). TRISS better predicted mortality than NSQIP-SRC or ASA-PS on Brier score (0.02 versus 0.03 versus 0.03) but all had similar area under the receiver-operating characteristic curve (0.93 versus 0.93 versus 0.91, P = 0.26). NSQIP-SRC and ASA-PS better predicted LOS on adjusted R
conclusionsFor penetrating trauma, all three models were similarly excellent at predicting mortality. NSQIP-SRC and ASA-PS better predicted LOS and NSQIP-SRC best predicted complications, suggesting these are better tools for prognostication of outcomes for penetrating trauma.
