Early Versus Delayed Antihypertensive Therapy in Acute Ischemic Stroke: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.
Article in Annals of Indian Academy of Neurology, 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
BACKGROUND AND
objectivesIschemic stroke remains a major global cause of death and morbidity. Hypertension is often found in this condition and is associated with poorer functional outcomes and higher mortality. This study aimed to evaluate the effectiveness of early antihypertensive therapy in acute ischemic stroke.
methodsThis study followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria. Literature searches in PubMed, the Cochrane Library, and ClinicalTrials.gov from database inception to October 20, 2025 included randomized controlled trials (RCTs) involving adults with ischemic stroke. The primary outcome was mortality; secondary outcomes included functional outcomes measured by the modified Rankin Scale (mRS), major vascular events, and recurrent stroke. Pooled effects were calculated using a random-effects model as an odds ratio with a 95% confidence interval. Heterogeneity was assessed using the I 2 statistic.
resultsThree RCTs were included. Early antihypertensive therapy showed no significant difference compared with delayed treatment in mortality or major disability at 90 days, good functional outcome (mRS: 0-2), or poor functional outcome (mRS: 3-6). No significant subgroup differences were observed. Early treatment also did not reduce the risk of major vascular events or recurrent stroke.
conclusionsCurrent evidence from a limited number of RCTs suggests that early antihypertensive therapy is not associated with improved mortality or major disability at 90 days, functional outcomes, vascular events, or recurrent stroke in patients with ischemic stroke. However, these findings should be interpreted with caution, given the small number of included studies, and further large-scale RCTs are needed.
