Prehospital blood pressure lowering in acute hemorrhagic stroke: a systematic review and meta-analysis of randomized controlled clinical trials.
Synthesis in European stroke journal, 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
introductionElevated blood pressure (BP) in acute hemorrhagic stroke has been associated with adverse clinical outcomes. Limited data from randomized controlled clinical trials (RCTs) indicate that early BP management, in the prehospital setting, may be safe and beneficial. We sought to evaluate the efficacy and safety of prehospital BP-lowering in acute hemorrhagic stroke when compared to usual care. PATIENTS AND
methodsWe conducted a systematic review and meta-analysis including available RCTs evaluating prehospital BP-lowering among acute hemorrhagic stroke patients. The pooled risk ratio (RR) of a 3-month good functional outcome, defined as modified-Rankin-Scale scores of 0-2 and all-cause 3-month mortality were the primary efficacy and safety outcomes, respectively. Secondary outcomes included the pooled RR of hematoma expansion (HE) and serious adverse events (SAEs).
resultsA total of four RCTs were included, comprising 642 patients treated with prehospital BP-lowering therapies and 617 patients receiving usual care. Prehospital BP-lowering was associated with similar rates of good functional outcome (RR: 1.07; 95% CI, 0.52-2.19) and all-cause mortality (RR: 0.90; 95% CI, 0.60-1.35) at 3 months, compared to usual care. The risk of SAEs (RR: 0.97; 95% CI, 0.74-1.26) and HE (RR: 1.05; 95% CI, 0.45-2.46) did not significantly differ between the two groups. Subgroup analyses revealed the superiority of the α-adrenoreceptor blocker urapidil compared to glyceryl trinitrate in terms of reducing SAE risk and HE.
conclusionOur meta-analysis indicates that prehospital BP-lowering in acute hemorrhagic stroke does not improve functional outcome and survival. Future RCTs conducted in mobile stroke units, and exclusively focusing on patients with acute hemorrhagic stroke, are required.
