1 · What the graph read from it

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.

2 · The registry

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

objectivesTo determine whether minority trauma patients are more commonly treated at trauma centers (TCs) with worse observed-to-expected (O/E) survival.

backgroundRacial disparities in survival after traumatic injury have been described. However, the mechanisms that lead to these inequities are not well understood.

methodsAnalysis of level I/II TCs included in the National Trauma Data Bank 2007-2010. White, Black, and Hispanic patients 16 years or older sustaining blunt/penetrating injuries with an Injury Severity Score of 9 or more were included. TCs with 50% or more Hispanic or Black patients were classified as predominantly minority TCs. Multivariate logistic regression adjusting for several patient/injury characteristics was used to predict the expected number of deaths for each TC. O/E mortality ratios were then generated and used to rank individual TCs as low (O/E <1), intermediate, or high mortality (O/E >1).

resultsA total of 556,720 patients from 181 TCs were analyzed; 86 TCs (48%) were classified as low mortality, 6 (3%) intermediate, and 89 (49%) as high mortality. More of the predominantly minority TCs [(82% (22/27) vs 44% (67/154)] were classified as high mortality (P < 0.001). Approximately 64% of Black patients (55,673/87,575) were treated at high-mortality TCs compared with 54% Hispanics (32,677/60,761) and 41% Whites (165,494/408,384) (P < 0.001).

conclusionsMinority trauma patients are clustered at hospitals with significantly higher-than-expected mortality. Black and Hispanic patients treated at low-mortality hospitals have a significantly lower odds of death than similar patients treated at high-mortality hospitals. Differences in TC outcomes and quality of care may partially explain trauma outcomes disparities.
