Duration of the posttraumatic confusional state after moderate and severe traumatic brain injury: impact of injury severity and preinjury factors.

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
Introduction: This study aimed to estimate the duration, of the posttraumatic confusional state (PTCS), and predictors of the duration after moderate and severe traumatic brain injury (TBI) in a prospective inception cohort. Materials and methods: In 424 surviving neurosurgical patients with moderate [Glasgow Coma Scale (GCS) score 9-13] or severe TBI (GCS score ≤ 8), PTCS duration was estimated from sources documenting confusion or amnesia. Associations between PTCS duration and age, sex, indices of injury severity, and proxies of cognitive (education) and brain reserve (preinjury brain-related disability) were analyzed using binary logistic regression. Results: The most common PTCS duration was ≤ 7 days in the moderate TBI group (58%) and >28 days in the severe TBI group (52%). In multivariable analyses, lower age ( Conclusion: Cognitive reserve was associated with short, but not long, PTCS, while the proxy of brain reserve was not associated with PTCS. Age and injury-related variables were most consistently associated with PTCS duration. These results support the notion that PTCS is a foreseeable clinical phase after TBI, determined mainly by the brain injury itself.
