A/BIC: Akaike/Bayesian information criteria; dof: degrees of freedom; ENI: early neurological improvement; HT: haemorrhagic transformation; NPV: negative predictive value; PPV: positive predictive value; ROC: receiver–operator characteristic curve.
Used as reference category.
P < 0.1 for enter and stay criteria. The two multivariate models differed in terms of the particular covariates/factors included.
P < 0.05 as the threshold for statistical significance.
