The Natural History and Reperfusion Therapy Outcomes of Acute Ischemic Stroke due to Isolated M2 Occlusions

Figure 1

Distribution of mRS scores at 90 days in the three groups. Notes: proportion of mRS scores at 90 days in patients in the NRT, IVT, and EVT groups. NRT: no reperfusion therapy; IVT: intravenous thrombolysis treatment; EVT: endovascular intervention; mRS: modified Rankin Scale. A 90-day mRS score of 0-1 was defined as an excellent outcome, an mRS score of 0-2 was defined as a good outcome, an mRS score of 3-5 was defined as a bad outcome, and an mRS score of 6 referred to death.
