Notes: Model 1 included age and sex; Model 2 included age, sex, 24 h NIHSS score, pre-treatment ASPECTS and poor collateral status; Model 3 included age, sex, pre-treatment ASPECTS, poor collateral status, baseline NIHSS score, successful reperfusion, stroke subtypes and diabetes mellitus.
Abbreviations: CI, confidence interval; IDI, integrated discrimination improvement; METS-IR, metabolic score for insulin resistance; NRI, net reclassification improvement; sICH, symptomatic intracranial hemorrhage.
