The primary outcome was the 90-day modified Rankin Scale score, assessed with mixed-effect ordinal regression models. Safety outcomes were any intracranial hemorrhage and symptomatic intracranial hemorrhage. A secondary analysis used inverse probability of treatment weighting. Treatment effect heterogeneity between IVT plus EVT and EVT alone was assessed in a 2-step meta-analysis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS:<\/jats:title>\n                    <jats:p>\n                      Overall, 340 of 2267 (15%) patients had carotid tandem lesions with 113 of 329 (34%) undergoing acute carotid stenting. Stenting was associated with better 90-day functional outcomes (adjusted common odds ratio, 1.60 [95% CI, 1.03\u20132.47]), confirmed in inverse probability of treatment weighting analysis (adjusted common odds ratio, 1.66 [95% CI, 1.08\u20132.54]). Patients undergoing stenting had no statistically significant higher rates of any intracranial hemorrhage (44% versus 35%; adjusted odds ratio, 1.30 [95% CI, 0.79\u20132.15]) and symptomatic intracranial hemorrhage (6.3% versus 3.7%; adjusted odds ratio, 2.09 [95% CI, 0.78\u20135.59]). No heterogeneity in treatment effect was observed in patients randomized to IVT plus EVT (adjusted common odds ratio, 2.07 [95% CI, 1.06\u20134.07]) or EVT alone (1.21 [95% CI, 0.59\u20132.50];\n
