We sought to assess the relationship between day-of-injury GFAP and cumulative prevalence (CI) of depression or suicidal ideation in the first year after injury among patients presenting with Glasgow Coma Scale 13\u201315 who participated in Transforming Research and Clinical Knowledge in Traumatic Brain Injury (n = 1511). Multivariable logistic regression models were used to assess the association of day-of-injury GFAP levels with year 1 CI of depression or suicidal ideation adjusting for age, sex, prior TBI, psychiatric history and acute intracranial trauma on head computed tomography (CT) scan. Subgroup analyses categorized into \u2018high\u2019 and \u2018low\u2019 risk for mental health problems based upon a history of psychiatric disorder or TBI. Overall, 20.4% reported depression and 11.3% reported suicidal ideation in the first year. Participants with depression had significantly lower GFAP compared with participants without depression overall (median = 149.9\u2005pg\/mL versus 306.9\u2005pg\/mL, P &amp;lt; 0.001) and CT-negative high risk and CT-negative low risk subgroups. Participants with suicidal ideation had lower GFAP in the overall sample (155.8\u2005pg\/mL versus 299.1\u2005pg\/mL, P = 0.001). We found an interaction between GFAP and CT status, reflecting an inverse association of GFAP with cumulative depression among CT\u2212 subjects (adjusted odds ratio = 0.84, 95% CI: 0.77\u20130.92), but not among CT+ subjects. Blood biomarkers may warrant future investigation as potential predictors of depression following TBI in patients without evidence of acute intracranial trauma on CT scan.<\/jats:p>","DOI":"10.1093\/braincomms\/fcaf123","type":"journal-article","created":{"date-parts":[[2025,3,29]],"date-time":"2025-03-29T06:35:11Z","timestamp":1743230111000},"source":"Crossref","is-referenced-by-count":1,"title":["Association
