TEK and Sepsis: This study was performed to assess the early diagnostic, risk stratification, and prognostic value of the angiopoietin-2/angiopoietin-1 ratio (Ang-2/Ang-1) and angiopoietin-1/tyrosine kinase with immunoglobulin-like loop epidermal growth factor homology domain 2 ratio (Ang-1/Tie-2) and to compare these factors with procalcitonin (PCT) and the Mortality in Emergency Department Sepsis (MEDS) score in patients with early sepsis in the emergency department (ED).
