Predictors of transitions between normal cognition, cognitive impairment, and dementia in a longitudinal cohort.

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
BackgroundUnderstanding how sociodemographic characteristics and medical history are associated with progression (or regression) of Alzheimer's disease and related dementias could inform intervention strategies, personalized prognoses, and projections of population-level burden.ObjectiveWe estimated transition rates for progression and reversion between normal cognition, cognitive impairment, dementia, and death in a longitudinal cohort, as well as associations with sociodemographic characteristics and medical history.MethodsWe applied a multistate transition model to a cohort of 960 participants (with 2-16 (median 3) annual visits; 2006-24). Covariate hazard ratios (HRs) were estimated in models adjusted for age group.ResultsSeveral covariates were associated with faster progression from normal cognition to cognitive impairment but slower progression from cognitive impairment to dementia. For example, non-Hispanic Black participants transitioned from normal to cognitive impairment at higher rates (HR: 2.29, 95% CI: 1.63, 3.21) and to dementia at lower rates (HR: 0.12, 95% CI: 0.06, 0.23) than non-Hispanic White participants. Additionally, amnestic versus non-amnestic impairment emerged as a strong predictor of transitions from cognitive impairment by reducing reversion to normal cognition (HR: 0.51, 95% CI: 0.35, 0.74) and accelerating progression to dementia (HR: 2.51, 95% CI: 1.49, 4.22). History of traumatic brain injury was associated with reversion from cognitive impairment to normal cognition (HR: 2.43, 95% CI: 1.13, 5.23).ConclusionsA better understanding and measurement of cognitive impairment is needed to explain and predict both reversion to normal cognition and why factors associated with faster onset of impairment may be associated with delayed onset of dementia.
