FactorsBetaOR95% CIP values
Age*−0.020.980.97 to 0.990.04
NIHSS* to 1.18<0.001
Large to very large infarct (vs small to medium infarct)0.892.441.57 to 3.79<0.001

  • *Entered as linear variables, where the OR reflected the expected change in odds for one-point increase in NIHSS or 1-year increase in age.

  • HAS, hyperdense artery sign; NIHSS, National Institute of Health Stroke Scale.
