However, their prognostic role in cerebral venous thrombosis remains uncertain. We aimed to assess the prognostic value of these biomarkers in acute cerebral venous thrombosis by identifying optimal thresholds and internally validating their predictive performance.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>METHODS:<\/jats:title>\n                    <jats:p>This retrospective observational cohort study included adults diagnosed with acute cerebral venous thrombosis from the international CLOT-VENUS registry (Collaboration on Cerebral Venous Thrombosis Study; 2004\u20132024), including 2 comprehensive stroke centers in the United States and Mexico. Biomarkers of interest (NLR, MLR, PLR, SII) were calculated from admission complete blood counts. The primary outcome was functional status at 6 months, measured by the modified Rankin Scale dichotomized as 0 to 2 versus 3 to 6. Secondary outcomes included modified Rankin Scale score at discharge and mortality. Associations were tested with multivariable logistic regression adjusted for clinically relevant covariates. Optimal biomarker cutoffs were identified using stratified bootstrap receiver operating characteristic analysis and internally validated with out-of-bag testing.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS:<\/jats:title>\n                    <jats:p>\n                      Of 432 patients, 394 met the inclusion criteria, and complete data were available for 339 of those patients. Median age was 40 years [interquartile range, 27\u201345], and 65.2% were female. Elevated biomarkers at admission were associated with modified Rankin Scale score 3 to 6 at discharge and 6 months.
