Analysis of the Efficacy and Safety of Recombinant Tissue Plasminogen Activator for Chinese Patients over 80 Years of Age with Acute Ischemic Stroke: A Pilot Study

Comparison of the modified Rankin score (mRS) among the three groups, 90 days after treatment. The percentage of patients with each mRS is color-coded and the percentage is shown in the color-coded bar. An mRS of 0–2 in the patients aged 60–80 was significantly more frequent than in both patient groups >80 years old, but an mRS of 0–2 in patients >80 years old who received rt-PA was not significantly more frequent than that of patients >80 years old who did not receive rt-PA treatment
