Table 3 Characteristics of patients with large vessel occlusion and a positive history of ischemic stroke, subdivided into patients with and without the intake of platelet aggregation inhibitors (PAI) or oral anticoagulants (OAC) at admission. For intergroup differences, chi-square test was used for binary variables and Mann-Whitney test for ordinal or numeric scaled variables, a p-value < 0.05 was considered significant and marked in bold. Abbreviations: NIHSS – National Institute of Health Stroke Scale, mRS – modified Rankin Scale
