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
backgroundComputed tomography (CT) is common for trauma victims, but is usually done without informing patients of potential risks or obtaining informed consent.
objectiveThe objective of this study was to determine the feasibility of two elements (time and normal level of alertness) necessary for informed consent for CT in adult trauma patients.
methodsWe conducted this prospective observational, two-phase cohort study at two urban, Level I trauma centers. In the first phase, we determined the median time needed to obtain informed consent for CT by performing sham consent on 11 injured patients at each site. In the second phase, we observed all adult trauma activation cases that presented during specified time blocks and recorded Glasgow Coma Scale (GCS) scores and the time available for consent (TAC) for CT-defined as the time between the end of the secondary trauma survey and when the patient left the resuscitation room to go to CT. We defined, a priori, feasible consent cases as those in which the patient had a GCS of 15 and a TAC greater than the median sham consent time at that site.
resultsThe median times for sham CT consent at the two sites were 3:36 and 2:09 minutes:seconds (range = 1:12-4:54). Of the 729 trauma patients enrolled during phase II, 646 (89%) had a CT scan, and of these 646 patients, 461 (71.4% [95% confidence interval = 67.8%- 74.7%]) met feasible consent criteria. Of the 185 patients who failed to meet feasible consent criteria, 171 (92.4%) had a GCS < 15, one (0.5%) had a TAC less than the sham consent time, and 13 (7.0%) had both.
conclusionWe found that informed consent for CT was likely feasible in over two-thirds of acute, adult trauma patients.
