A Cochran-Armitage trend test was used. Results are expressed as percentages or as means (SD); I.S., ischemic stroke; BT-SM, brain tumor-stroke mimics; TF-UP, transferrin unique peptide; LRP, labeled reference peptide; IHD, ischemic heart diseases; Serum TF-UP/LRP level: low, 0– <0.4; medium, 0.4– <0.8; high, 0.8–1.2.
