Note. ANOVA = analysis of variance; VIF = variance inflation factors; LOS = length of stay; ICU = intensive care unit; TPP = third party payer; IS = ischemic stroke; TIA = Transit Ischemic Attack; PICH = primary Intracerebral hemorrhage; SAH = subarachnoid hemorrhage; NIHSS = National Institution of Health Stroke Scale; mRS = modified Rankin Scale; BI = Barthel Index; TOAST = Trial of Org 10172 in Acute Stroke Treatment; LA = large-artery atherosclerosis; CE = cardioembolism; SV = small-vessel occlusion; UC = unclassified; LACS = lacunar stroke syndrome; PACS = partial anterior circulation stroke; POCS = posterior circulation stroke; TACS = total anterior circulation stroke.

Dependent variable: ln(cost). Independent variables: LOS, ICU LOS, TPP, surgery, type of stroke, NIHSS at admission, mRS at discharge, infectious complication, BI at discharge, discharge destination, sex, age.
