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

objectiveAgitation is a major problem in the intensive care unit. However, no treatment has clearly emerged as effective and safe. Using target trial emulation, we aimed to test the hypothesis that early intervention with dexmedetomidine would accelerate agitation resolution.

methodsWe read clinical notes in an electronic medical records system with natural language processing to identify patients with agitation. We obtained their demographics, trajectories, associations, and outcomes. We used g-formulas to study the possible effects of dexmedetomidine on agitation resolution and key outcomes.

resultsWe screened 7525 patients. Overall, 2242 patients (29.8%) developed within-intensive care unit agitation, and 2052 (27.3%) were eligible for inclusion in the target trial emulation, with 314 treated with dexmedetomidine. Dexmedetomidine-treated patients had more severe illness and were more likely to have unplanned emergency admissions with medical diagnoses. However, they achieved higher rates of resolution of within-intensive care unit agitation (94% versus 72%; p < 0.001) and lower 30-day mortality (5% versus 9%; p = 0.033). Early initiation of dexmedetomidine accelerated the resolution of agitation (risk ratio [RR] 1.13 [95%CI 1.03 - 1.21]; risk difference [RD] 9.8% [95%CI 2.6% - 15.4%]); extubation by Day 30 (RR 1.03 [95%CI 1.02 - 1.04]; RD 3.1% [95%CI 2.2% - 4.2%]); and reduced the chance of having a tracheostomy by Day 30 (RR 0.67 [95%CI 0.34 - 0.99]; RD -3.5% [95%CI -7.0% - -0.0%]).

conclusionThrough target trial emulation analysis, early dexmedetomidine was associated with an increased rate of resolution of agitation and extubation and decreased tracheostomy risk.
