Among common neuropsychological tests, the Paced auditory serial addition test is the strongest predictor of trait fatigue in patients with traumatic brain injury.

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
Fatigue is one of the most common symptoms following traumatic brain injury (TBI). Despite its prevalence, fatigue remains a challenging concept to define and measure. The aim of the present study was to explore potential relationships between self-rated fatigue in patients with TBI and performance on several widely used neuropsychological tests. In a cross-sectional design, patients with TBI (n = 68) and healthy controls (n = 27) underwent a comprehensive battery of commonly used neuropsychological tests and completed two self-assessment fatigue scales, the Fatigue Severity Scale and the Mental Fatigue Scale. Patients with TBI performed worse on neuropsychological tests of short-term memory, processing speed and executive functioning (inhibition) compared to healthy controls. Within the TBI group, only the Paced Auditory Serial Addition Test (PASAT) and the Stroop-Inhibition task showed significant correlations with measures of fatigue. However, after adjusting for relevant demographic variables, including age, gender, education and TBI severity, only PASAT remained significantly associated with the Mental Fatigue Scale (r = .45, p = .005). Within the healthy control group, no such associations were found. These results highlight an interesting relationship between PASAT performance and self-assessed fatigue. With further research, PASAT, modifications of it or similar measures could potentially help clinicians in evaluating fatigue in patients with TBI.
