Traumatic Brain Injury and Depressive Symptoms in Community-Dwelling Older Adults: A Prospective Cohort Study.
Article in Neurology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
BACKGROUND AND
objectivesMood symptoms are recognized short-term sequelae of traumatic brain injury (TBI). Research regarding depressive symptoms among older, community-based individuals with TBI is limited. Previous studies have largely focused on short-term and intermediate-term follow-up.
methodsThe Atherosclerosis Risk in Communities study is an ongoing prospective cohort study of community-dwelling adults in the United States, initially recruited from 1987 to 1989. TBI was defined using self-reported and International Classification of Diseases diagnostic codes. Participants were sampled from centers in Maryland, Minnesota, Mississippi, and North Carolina. Depressive symptoms and antidepressant prescription(s) were assessed beginning at visit 5 (2011-2013) and were analyzed as time-varying repeated outcome measures until visit 7 (2018-2019), representing a maximum follow-up interval of 9 years. We used generalized estimating equations (GEEs) with an autoregressive working correlation structure and binomial distribution with a log link to estimate risk ratios (RRs) for the association of TBI with time-varying depressive symptoms and antidepressant prescription(s), adjusting for sociodemographic characteristics including age, race and study center, income, educational attainment, and history of military service.
resultsOur analysis included 6,607 individuals who attended at least 1 study visit between visits 5 and 7. The median age was 75 years (25th-75th percentiles = 72-80). More than half were female (59.0%), and 23.7% self-identified as Black. There were 2,113 participants (32.0%) with a lifetime history of TBI, most of which were classified as mild. There were 665 individuals (10.1%) who experienced depressive symptoms and 1,225 (18.5%) with antidepressant prescriptions recorded during follow-up. In fully adjusted GEE models, TBI was associated with an increased risk of depressive symptoms (RR 1.59, 95% CI 1.37-1.85) and antidepressant use (RR 1.32, 95% CI 1.20-1.45). These results persisted in analysis of subgroups defined by age, sex, race, and participant health characteristics, regardless of TBI frequency or severity. DISCUSSION: We observed a robust and persistent association of TBI with depressive symptoms and antidepressant prescriptions in this cohort of older, community-dwelling adults regardless of participant characteristics. These results suggest that universal screening for and prompt treatment of depressive symptoms in among older adults with a history of TBI is warranted.
