Association of a novel nutritional marker, the triglyceride-cholesterol-body weight index, with 90-day unfavorable outcomes in acute ischemic stroke: a prospective cohort study

Objective Currently, research on the relationship between triglyceride-total cholesterol-body weight index (TCBI) and prognosis in patients with Acute Ischemic Stroke (AIS) is relatively limited. Therefore, this study aims to investigate the association between TCBI and the incidence of unfavorable functional outcomes in AIS patients. Methods This secondary analysis included 1,764 AIS patients admitted to a South Korean hospital from January 2010 to December 2016. Binary logistic regression assessed the association between TCBI and 90-day unfavorable outcomes (defined as mRS score ≥3). A logistic regression model with restricted cubic spline functions was employed to explore the potential nonlinear…
