1 · What the graph read from it

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.

2 · The registry

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

We compared the rates of recanalization cerebral infarct and hemorrhage between intra-arterial (i.a.) reteplase and intravenous (i.v.) alteplase thrombolysis in a canine model of basilar artery thrombosis. Thrombosis was induced by injecting a clot in the basilar artery of 13 anesthetized dogs via superselective catheterization. The animals were randomized in a blinded fashion, 2 h after clot injection and verification of arterial occlusion, to receive i.v. alteplase 0.9 mg/kg over 60 min and i.a. placebo, or i.a. reteplase 0.09 units/kg over 20 min, equivalent to one-half the alteplase dose, and i.v. placebo. Recanalization was studied for 6 h after treatment with serial angiography; the images were later graded in a blinded fashion. Blinded interpretation of postmortem MRI was performed to assess the presence of brain infarcts and/or hemorrhage. At 3 h after initiation of treatment, partial or complete recanalization was observed in one of six dogs in the i.v. alteplase group and in five of seven in the i.a. reteplase group (P = 0.08). At 6 h, no significant difference in partial or complete recanalization was observed between the groups (two of six vs. five of seven; P = 0.20). Postmortem MRI revealed infarcts in four of six animals treated with i.v. alteplase and three of seven treated with i.a. reteplase (P = 0.4). Intracerebral hemorrhage was more common in the i.v. alteplase group (four of six vs. none of seven; P = 0.02). This study thus suggests that i.a. thrombolysis affords a recanalization rate similar to that of i.v. thrombolysis, but with a lower rate of intracerebral hemorrhage.
