  1. Values were measured for the peak body temperature within 24 hours following mechanical thrombectomy
  2. Abbreviations: BT body temperature, mRS modified Rankin Scale, OR odds ratio, HT hemorrhage transformation, HI hemorrhagic infarction, SAH subarachnoid hemorrhage, sICH symptomatic intracranial hemorrhage
  3. † The multiple logistic regression test was used to analyze ORs. Adjusted variables: age, sex, length of stay, NIHSS score at baseline, atrial fibrillation, smoking, serum glucose level, SBP, WBC, procedure time, successful reperfusion and number of devices passes
  4. ‡ The Bonferroni correction method was used to assess the primary and secondary outcomes, and a P value <0.05/number of comparisons was used as the threshold for statistical significance (P<0.025 for primary outcomes and P<0.008 for secondary outcomes)
