Magnitude of systolic blood pressure reduction following endovascular treatment and clinical outcomes in acute large artery occlusion stroke.
Observational study in Stroke and vascular neurology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe impact of lowering systolic blood pressure (SBP) following endovascular treatment (EVT) in acute large vessel occlusion stroke (LVOS) patients remains unclear. We aimed to explore the effect of the magnitude of SBP reduction (SBPr) after EVT on outcomes in LVOS patients.
methodsWe consecutively registered patients at three comprehensive stroke centres who had experienced EVT as a result of acute anterior circulation LVOS. SBPr was calculated as follows: (baseline SBP-mean SBP/baseline SBP)×100%. The 90-day modified Rankin Scale score ranging from 0 to 2 was defined as a favourable functional outcome. Based on CT scans obtained within 24 hours after procedure, symptomatic intracranial haemorrhage (sICH) was assessed according to the criteria of the European Cooperative Acute Stroke Study III.
resultsWe enrolled 1080 patients, of which 908 (84.1%) had successful recanalisation. In the overall cohort, SBPr was correlated with lower odds of sICH (SBPr±10% as a reference, 20%-30%: OR 0.460; 95% CI: 0.245 to 0.864; p=0.016; >30%: OR 0.304; 95% CI 0.123 to 0.749; p=0.010). In patients who achieved successful reperfusion, SBPr>30% was correlated with higher odds of a poor outcome (SBPr±10% as a reference, OR 2.150; 95% CI 1.268 to 3.645; p=0.004) and SBPr has a similar tendency towards reducing the incidence of sICH. In the subgroup analyses, baseline Alberta Stroke Programme Early CT (ASPECT) score (p
conclusionAmong patients with EVT, a significant drop in SBP may be related to a poor functional outcome and a reduced incidence of sICH. Baseline ASPECT score may be an important interacting factor in the association of SBPr with the 90-day outcome. This study provides new insights for individualised BP management in patients with EVT.
