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
backgroundUncertainty persists regarding the optimal systolic blood pressure (SBP) target after thrombectomy, as systemic blood pressure may affect the penumbra and associated microcirculatory perfusion. We evaluated the impact of different SBP targets on outcomes and the dose-response relationship between actual 24-hour mean SBP and functional outcomes.
methodsWe systematically reviewed studies comparing SBP targets after thrombectomy. Bayesian network meta-analysis assessed functional independence and safety. Multi-threshold sensitivity analyses tested the proportional odds assumption across disability levels. Study-level meta-regression explored the association between 24-hour mean SBP and functional outcomes.
resultsEight studies were included. The < 180 mmHg target ranked highest for functional independence (SUCRA = 87.3% (50.0%-100.0%)), while < 140 mmHg (SUCRA = 26.3%, OR = 1.65 (1.03-2.54)) and < 120 mmHg (SUCRA = 17.7%, OR = 1.75 (1.14-2.71)) were associated with worse outcomes, and the certainty of the evidence was high. No significant differences in symptomatic intracranial hemorrhage or 90-day mortality were observed. Among six study-level comparisons, five violated the proportional odds assumption, indicating effect heterogeneity across disability levels.An exploratory group-level meta-regression showed that, within the observed range of 117-139 mmHg, higher actual SBP was associated with a higher odds ratio for functional independence at the study group level (OR = 1.028 (1.015-1.041)).
conclusionsAfter successful recanalization, clinicians should avoid excessive SBP reduction. Future studies should consider reperfusion status, the burden of ischemic injury, and tissue perfusion to determine individualized blood pressure targets.
