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

This study revealed an independent negative link between TCBI and unfavorable outcomes at 90 days in patients with AIS. A nonlinear relationship between them was observed. When TCBI values were below 1227.3, a significant negative correlation was found. This provides new insights for prognostic stratification, optimization of rehabilitation strategies, and clinical management in AIS patients.
