The extracted data included sample size, patient age, National Institutes of Health Stroke Scale (NIHSS) scores, 90-day modified Rankin Scale (mRS) scores of 0\u20132 and 0\u20133, mortality rates, symptomatic intracranial hemorrhage (sICH), and occurrence of subarachnoid hemorrhage (SAH).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Five studies that included a total of 1,578 patients (594 IVT\u2009+\u2009EVT vs. 984 EVT), met the inclusion criteria and were analyzed. The meta-analysis demonstrated that bridging IVT was associated with a higher likelihood of achieving a 90-day mRS score of 0\u20132 (41% vs. 34%; OR\u2009=\u20091.35, 95% CI 1.09\u20131.68,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.006). Furthermore, the mortality rate was significantly lower in the IVT\u2009+\u2009EVT group than in the direct EVT group (25% vs. 30%; OR\u2009=\u20090.70, 95% CI 0.55\u20130.89,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.003), with low heterogeneity observed (\n                      <jats:italic>I<\/jats:italic>\n                      <jats:sup>2<\/jats:sup>\n                      =\u20090.0%,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.78).

In addition, the benefit of bridging IVT to EVT appeared to be more pronounced in European patients than in Asian patients compared to EVT alone. However, the conclusions of this study are not definitive and require validation through large-scale randomized controlled trials (RCTs) to draw more robust conclusions.<\/jats:p>\n
