  1. Values were measured for the peak body temperature within 24 hours following mechanical thrombectomy
  2. Abbreviations: TIA transient ischemic attack, LDL-C low-density lipoprotein cholesterol, HDL-C high-density lipoprotein cholesterol, ICA internal carotid artery, MCA middle cerebral artery, TOAST trial of ORG 10172 in acute stroke treatment, NIHSS National Institutes of Health Stroke Scale, TICI thrombolysis in cerebral infarction, ASPECs Alberta Stroke Program Early CT Score, MT mechanical thrombectomy
  3. * Continuous variables were compared between groups using independent samples t tests, Mann-Whitney U tests, or Kruskal-Wallis H tests. Categorical variables were analyzed by χ2 test, or Fisher’s exact tests as appropriate
  4. a Successful recanalization indicates the TICI score of 2b-3
