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

introductionWhole blood resuscitation is associated with survival benefits in observational cohort studies. The mechanisms responsible for outcome benefits have not been adequately determined. We sought to characterize the achievement of hemostasis across patients receiving early whole blood versus component resuscitation. We hypothesized that achieving hemostasis would be associated with outcome benefits and patients receiving whole blood would be more likely to achieve hemostasis.

methodsWe performed a post hoc retrospective secondary analysis of data from a recent prospective observational cohort study comparing early whole blood and component resuscitation in patients at risk of hemorrhagic shock. Achievement of hemostasis was defined by receiving a single unit of blood or less, including whole blood or red cells, in any 60-minute period, over the first 4 hours from the time of arrival. Time-to-event analysis with log-rank comparison and regression modeling were used to determine the independent benefits of achieving hemostasis and whether achieving hemostasis was associated with whole blood resuscitation.

resultsFor the current analysis, 1,047 patients met the inclusion criteria for the study. When we compared patients who achieved hemostasis versus those who did not, achievement of hemostasis had significantly more hemostatic coagulation parameters, had lower transfusion requirements, and was independently associated with 4-hour, 24-hour and 28-day survival. Whole blood patients were significantly more likely to achieve hemostasis (88.9% vs. 81.1%, p < 0.001). Whole blood patients achieved hemostasis earlier (log-rank χ 2 = 8.2, p < 0.01) and were independently associated with over twofold greater odds of achieving hemostasis (odds ratio, 2.4; 95% confidence interval, 1.6-3.7; p < 0.001).

conclusionAchievement of hemostasis is associated with significant outcome benefits. Early whole blood resuscitation is associated with a greater independent odds of achieving hemostasis and at an earlier time point. Reaching a nadir transfusion rate early following injury represents a possible mechanism of whole blood resuscitation and its attributable outcome benefits.
