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
Objective: To exemplify the use of the Coma Recovery Scale-Revised (CRS-R) during critical acute care and to characterize associated functional and rehabilitative trajectories of patients with disorders of consciousness (DoC). Although most research emphasizes postacute assessment and recovery, early rehabilitation in the initial days and weeks after injury remains unexplored. Design: Retrospective, observational cohort study. Setting: Level 1 Trauma and Certified Stroke Center acute care hospital. Participants: A total of 68 adults admitted with a severe brain injury with an initial Glasgow Coma Scale score of ≤8. Main Outcome Measures: Outcomes were assessed across 3 domains: (1) consciousness, via the CRS-R; (2) respiratory function, including cough categorization, tracheostomy status, and decannulation readiness trials (speaking valve or capping); and (3) swallowing/eating, measured by the Functional Oral Intake Scale (FOIS) and engagement in evaluations for oral diet advancement. Results: Initial CRS-R assessments showed 2.9% (n=2) in coma, 52.9% (n=36) in unresponsive wakefulness syndrome (UWS), 27.9% (n=19) in minimally conscious state minus (MCS-), 13.2% (n=9) in MCS plus (MCS+), and 2.9% (n=2) emerged. By discharge, no patients remained in coma; 2.9% (n=2) were in UWS, 17.7% (n=12) MCS-, 13.2% (n=9) MCS+, and 41.2% (n=28) emerged. Among those emerging, 53.6% did so within 30 days. Tracheostomy was required in 73.5% (n=50); most participated in capping (72%, n=36/50) and speaking valve trials (88%, n=44/50) while cannulated, and 68% (n=34/50) were decannulated. Instrumental swallowing evaluations were completed in 42.6% (n=29), with 39.7% (n=27) discharged on oral diets. Overall, under half (39.7%, n=27) were discharged to specialized or rehabilitative settings. Conclusion: Patients with DoC make demonstrable improvements in consciousness, respiratory function, and swallowing during acute care, challenging prevailing assumptions that rehabilitation potential begins later in the recovery trajectory. These findings underscore the importance of initiating structured assessments and interventions early to optimize outcomes and inform discharge planning. Future research should focus on the development and evaluation of standardized screening protocols for identifying DoC in acute care, as well as examining national screening, assessment, and treatment practices.
