First-Line Vasopressor and Mortality Rates in ED Patients with Acute Drug Overdose.

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
introductionWhile emergency department (ED) visits for acute drug overdose are at an all-time high, the importance of vasopressors to treat circulatory shock in this patient population remains unclear. This study investigated the association between first-line vasopressor and mortality, for both push-dose and infusion, in this patient population.
methodsFrom a prospective cohort of consecutive ED patients with drug overdose at two urban teaching centers over 5 years, we performed a secondary data analysis of patients with circulatory shock, defined as hypotension requiring either vasopressors, high-dose insulin euglycemia therapy, or both. The first-line vasopressor (push-dose and infusion) was analyzed for associations with the primary outcome (in-hospital mortality) and secondary outcomes (24-hour mortality, ICU LOS). Subgroup analysis of beta-/calcium-channel blocker overdose was performed to evaluate impact of antidotal therapies. Data analysis included multivariable regression.
resultsFifty-five patients with circulatory shock were analyzed, in whom there was 20% 24-hour mortality, 42% in-hospital mortality, 730-minute mean vasopressor duration, and 53.4-hour median ICU LOS. On multivariable analysis, there was significantly decreased adjusted odds of in-hospital mortality with first-line push-dose phenylephrine (aOR 0.06, CI 0.01-0.55), and significantly increased adjusted odds of in-hospital mortality with first-line push-dose epinephrine (aOR 60.8, CI 6.1-608). Of the first-line infusions, norepinephrine had the lowest odds of in-hospital mortality (aOR 0.80, CI 0.2-3.1).
conclusionsIn ED patients with undifferentiated drug overdose and circulatory shock, the first-line vasopressor is associated with in-hospital mortality. First-line push-dose phenylephrine was associated with the lowest odds of in-hospital mortality. Future randomized studies are warranted for validation.
