Guideline for economic evaluations in healthcare [21]

  1. *Cost of the average treatment was adjusted for the estimated frequency of the treatment according to different studies. For IAT eligible patients, we assumed 85% to receive both IAT and intravenous thrombolysis (IVT), 10% to receive IAT only, and 5% to receive IVT and going for IAT but who appeared revascularised during angiography [3, 15, 24]. For non-IAT-eligible patients we assumed 40% to receive IVT based on previous study and our local medical center data[25]
  2. IAT, intra-arterial thrombectomy; mRS, modified Rankin Scale Costs are rounded to the nearest integer
