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 if changes in pelvic trauma care and treatment protocols have affected overall mortality rates after pelvic ring injury.

designRetrospective cohort study.

settingLevel I trauma center. PATIENTS/

participantsA total of 3314 patients with pelvic ring injuries who presented to a single referral center from 1999 to 2018 were included in the study.

interventionPelvic ring management, years 1999-2006 versus years 2007-2018. MAIN OUTCOME MEASUREMENTS: In hospital mortality. Other examined variables included change in patient demographics, fracture characteristics, date of injury, associated injuries, length of hospital stay, Abbreviated Injury Severity Score.

resultsThe composite mortality rate was 6.5% (214/3314). The earliest cohort presented a mortality rate of 9.1% [111/1224; 95% confidence interval (CI), 7.6%-10.8%] compared with the more recent cohort mortality rate of 4.9% (103/2090; 95% CI, 4.1%-5.9%). Overall mortality was significantly lower in the more recent period, a risk difference of 4.1% (95% CI, 2.3%-6.1%; P < 0.01). After adjusting for age and Abbreviated Injury Severity Score of the brain, chest, and abdomen, the mortality reduction was more pronounced with an adjusted risk difference of 6.4% (95% CI, 4.7%-8.1%; P < 0.01).

conclusionSignificant improvement in the mortality rate of pelvic ring injuries has been demonstrated in recent years (4.9% vs. 9.1%) and the difference is even large when accounting for known confounders. Improvement appears to coincide chronologically with changes in trauma resuscitation and implementation of adjuvant treatments for managing patients with severe hemorrhagic shock. Although the exact benefit of each treatment awaits further research, these data might indicate improved care over time for these difficult patients. LEVEL OF EVIDENCE: Therapeutic Level III.
