Systolic blood pressure within 24 hours after successful reperfusion correlates with outcomes in acute ischemic stroke: a secondary analysis of the EHCHANTED2/MT Trial.
Trial report in Journal of neurointerventional surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 optimal threshold or range for systolic blood pressure (SBP) control in patients with successful reperfusion after endovascular thrombectomy for acute ischemic stroke (AIS) remains undefined. This study investigated whether SBP within the first 24 hours after successful reperfusion correlates with functional outcomes in AIS.
methodsIn this secondary analysis of the ENCHANTED2/MT trial, patients were categorized into two groups (120-140 mm Hg and 140-180 mm Hg, respectively) based on achieved SBP within 24 hours after randomization. The primary outcome was the modified Rankin Scale (mRS) score at 90 days. Secondary outcomes included neurological deterioration at 7 days, major disability (mRS score of 3-5 at 90 days), hospitalization duration, and health-related quality of life assessed by the three-level EuroQoL 5-Dimension Self-Report Questionnaire (EQ-5D-3L) at 90 days. Safety outcomes included early neurological decline (END), 90-day mortality, symptomatic intracranial hemorrhage (sICH), and any intracranial hemorrhage (ICH). Treatment effects were expressed as ORs with 95% confidence intervals (CIs).
resultsA total of 611 patients (363 in the 120-140 mm Hg group and 248 in the 140-180 mm Hg group) were included. The mean (SD) age was 67 (12) years and 37.8% were female. After adjusting for confounders, the 120-140 mm Hg group was significantly associated with better functional outcomes (mRS: 2 (IQR 1-4) vs 2 (IQR 1-5); adjusted OR 1.54 (95% CI 1.10 to 2.17), P=0.013). Compared with the 140-180 mm Hg group, the 120-140 mm Hg group had lower rates of neurological deterioration at 7 days (adjusted OR 0.68 (95% CI 0.47 to 0.98), P=0.037) and 90-day mortality (47 (13.0%) vs 53 (21.4%); adjusted OR 0.48 (95% CI 0.27 to 0.86), P=0.013). There were no significant differences between groups in END, major disability at 90 days, hospitalization duration, EQ-5D-3L score, sICH, or ICH (all P>0.05).
conclusionsIn patients with successful reperfusion after endovascular thrombectomy, an average SBP within 24 hours of 120-140 mm Hg was associated with a greater likelihood of functional independence compared with 140-180 mm Hg.
