In this systematic review and meta-analysis, we examined factors influencing outcomes in adult patients with TBI, from 3 months to 1 year after injury. A search of four electronic databases\u2014PubMed, Scopus, Web of Science, and ScienceDirect\u2014yielded 29 studies for review and 16 for meta-analysis, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. In patients with TBI of any severity, mean differences were observed in age (8.72 years; 95% confidence interval [CI], 4.77\u201312.66 years), lymphocyte count (\u22120.15 109\/L; 95% CI, \u22120.18 to \u22120.11), glucose levels (1.20 mmol\/L; 95% CI, 0.73\u20131.68), and haemoglobin levels (\u22120.91 g\/dL; 95% CI, \u22121.49 to \u22120.33) between those with favourable and unfavourable outcomes. The prevalence rates of unfavourable outcomes were as follows: abnormal cisterns, 65.7%; intracranial pressure above 20 mmHg, 52.9%; midline shift of 5 mm or more, 63%; hypotension, 71%; hypoxia, 86.8%; blood transfusion, 70.3%; and mechanical ventilation, 90%. Several predictors were strongly associated with outcome. Specifically, age, lymphocyte count, glucose level, haemoglobin level, severity of TBI, pupillary reaction, and type of injury were identified as potential predictors of long-term outcomes.<\/jats:p>","DOI":"10.24171\/j.phrp.2023.0288","type":"journal-article","created":{"date-parts":[[2024,2,4]],"date-time":"2024-02-04T21:27:31Z","timestamp":1707082051000},"page":"3-17","update-policy":"https:\/\/doi.org\/10.24171\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Predictors
