1 · What the graph read from it

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.

2 · The registry

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

BACKGROUND AND

objectiveDelirium may occur in patients with traumatic brain injury (TBI), but this may be a marker for subsequent cognitive decline post-TBI. We aimed to compare cognitive outcomes and all-cause mortality between TBI patients with and without delirium.

methodsWe conducted a retrospective cohort study using the TriNetX global federated research network. We compared TBI patients who developed delirium within 14 days of TBI diagnosis with those who did not. The primary outcome was the 2-year composite risk of dementia, vascular dementia and Alzheimer's disease. Secondary outcomes included dementia, vascular dementia, Alzheimer's disease and all-cause mortality. Pre-specified subgroup analyses were performed in female patients, older adults (≥ 75 years), and individuals with substance use.

resultsTBI patients with delirium (n = 2564; mean age, 66.6 ± 19.4 years; 59.4% male), when compared with TBI patients without delirium (n = 667,950; mean age, 48.0 ± 25.1 years; 60.3% male), had more baseline comorbidities, including psychiatric disease, cerebrovascular disease and ischemic heart disease. After propensity score matching, TBI patients with delirium, compared with those without delirium, had a higher 2-year risk of the primary composite outcome (HR, 2.47; 95% CI, 1.84-3.31), as well as dementia (HR, 2.63; 95% CI, 1.92-3.60), vascular dementia (HR, 2.76; 95% CI, 1.45-5.24) and Alzheimer's disease (HR, 2.23; 95% CI, 1.21-4.09).

conclusionDelirium following TBI is associated with an increased risk of dementia and Alzheimer's disease. Delirium post-TBI may be a marker or a contributing factor to long-term cognitive decline in TBI patients.
