Recombinant Human Tissue Kallikrein-1 for Treating Acute Ischemic Stroke and Preventing Recurrence.
Review in Stroke, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Novel strategies are needed for the treatment of acute ischemic stroke when revascularization therapies are not clinically appropriate or are unsuccessful. rKLK1 (recombinant human tissue kallikrein-1), a bradykinin-producing enzyme, offers a promising potential solution. In animal studies of acute stroke, there is a marked 36-fold increase in bradykinin B2 receptor on brain endothelial cells of the ischemic region. Due to this environment, rKLK1-generated bradykinin will exert a potent local vasodilation and increase brain perfusion via 3 synergistic signaling pathways downstream to the B2 receptor. Because of its preferential effect on ischemic tissue, systemic adverse effects such as hypotension are avoided with proper dosing. In addition, with initial vasodilation through recruitment of preexisting collaterals, rKLK1 promotes long-term benefit of brain perfusion by promoting new collateral formation. With an extended course of therapy for weeks after acute ischemic stroke, these multifaceted effects may also reduce the risk of stroke recurrence. A prior phase II trial demonstrated a favorable impact on clinical outcomes and recurrent strokes, particularly among patients who were not eligible for mechanical thrombectomy. A phase II/III trial has launched in this population, though opportunities for combination revascularization therapies deserve further investigation.
