Course of Fatigue and Sleep After Moderate to Severe Traumatic Brain Injury.
Observational study in The Journal of head trauma rehabilitation. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo examine the development of different dimensions of fatigue and subjective and objective measures of sleep in the first 18 months post moderate to severe traumatic brain injury (TBI), and explore the association with biological (processing speed), psychological (mood), and social (restrictions in participation) factors across time.
participantsForty-two participants with moderate-severe TBI (45 ± 16 years old, 33% female).
designLongitudinal multicenter observational cohort study with 4 measurements (3, 6, 12, and 18 months post-injury). MAIN MEASURES: Dimensions of fatigue (Fatigue Severity Scale, FSS; Dutch Multifactor Fatigue Scale, DMFS), subjective (Pittsburgh Sleep Quality Index, PSQI) and objective sleep (actigraphy), processing speed (Symbol Digit Modalities Task, SDMT), mood (Hospital Anxiety and Depression Scale, HADS), and restrictions in participation (Utrecht Scale for Evaluation and Rehabilitation-Participation, USER-P).
resultsResults showed reduced sleep quality (PSQI: poor sleep quality at 3 months 41%; 6 months 43%; 12 months 56%; 18 months 43%) and high levels of fatigue (FSS: severe fatigue at 3 months 41%; 6 months 38%; 12 months 33%; 18 months 34%) with no significant changes over time. Physical fatigue (DMFS: β = -0.11, P = .007) and total sleep time (β = -0.14, P = .015) decreased over time. More mood problems were associated with worse sleep quality (PSQI; β = 0.35, P = .021), shorter total sleep time (β = 0.14, P = .046), and higher levels of fatigue (FSS: β = 0.20, P = .036; DMFS-mental: β = 0.36, P = .028; DMFS-physical: β = 0.36, P = .029). Restrictions in participation were associated with fatigue but not with sleep.
conclusionsHigh and stable levels of fatigue and poor sleep quality in the first 18 months following moderate-severe TBI were found. These symptoms were associated with mood problems. Assessment and treatment of fatigue and sleep problems should be included in clinical practice. In line with other studies, we suggest that mood interventions might aid the treatment for fatigue and sleep quality.
