Association between vasopressor use and mortality in patients with severe traumatic brain injury: a nationwide retrospective cohort study in Japan.

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
aimVasopressors are frequently incorporated into severe traumatic brain injury management algorithms. However, evidence regarding their clinical effectiveness is lacking. We undertook a nationwide retrospective cohort study to determine the association between vasopressor use and mortality in patients with severe traumatic brain injury.
methodsData were collected between January 2004 and December 2018 from the Japanese Trauma Data Bank, which includes data from 272 emergency hospitals in Japan. Adults aged 16 years and over with severe traumatic brain injury but without major extracranial injuries were examined. A severe traumatic brain injury was defined based on a Glasgow Coma Scale score of 3-8 on admission. Multivariable analysis and propensity score matching were carried out. Statistical significance was assessed using 95% confidence intervals.
resultsIn total, 10,295 patients were eligible for analysis, with 654 included in the vasopressor group and 9,641 included in the nonvasopressor group. The proportion of deaths at hospital discharge was higher in the vasopressor group than in the nonvasopressor group (81.80% [535/654] versus 40.24% [3,880/9,641]). This finding was confirmed in a multivariable logistic regression analysis (adjusted odds ratio, 5.37; 95% confidence interval, 4.23-6.81). Among propensity score-matched patients adjusted for severity, the proportion of deaths at hospital discharge remained higher in the vasopressor group than in the nonvasopressor group (81.87% [533/651] versus 56.22% [366/651]) (odds ratio, 3.52; 95% confidence interval, 2.73-4.53).
conclusionThe study results suggest that vasopressor use in patients with severe isolated traumatic brain injury is associated with a higher mortality at hospital discharge.
