Admission systolic blood pressure and shift towards poorer functional outcome after EVT, with and without prior IVT.
EVT: endovascular treatment; IVT: intravenous thrombolysis; mRS: modified Rankin Scale.
The graph depicts the log odds for a shift towards poorer modified Rankin Scale (mRS) score with corresponding 95% CI, for admission systolic blood pressure (SBP) level, with practically parallel lines for prior intravenous thrombolysis (IVT) and no prior IVT (p-value for interaction: 0.94). Admission SBP ranged from 84 to 260 mmHg. In patients with BP exceeding 185/110 mmHg, SBP lowered to below this threshold before enrolment.
