Engineered virus-like nanoparticles reverse heparin anticoagulation more consistently than protamine in plasma from heparin-treated patients.
Article in Thrombosis research, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Heparin is widely used for anticoagulation, often requiring the subsequent administration of a reversal agent. The only approved reversal agent for heparin is protamine sulfate, which induces well described adverse reactions in patients. Previously we reported a novel class of heparin antagonists based on the bacteriophage Qβ platform, displaying polyvalent cationic motifs which bind with high affinity to heparin. Here we report heparin reversal by the most effective of these virus-like particles (VLP) in samples from patients who were administered heparin during cardiac procedures or therapeutically for treatment of various thrombotic conditions. The VLP consistently reversed heparin in these samples, including those from patients that received high doses of heparin, with greater efficiency than a negative control VLP and with significantly less variability than protamine sulfate. These results provide the first step towards validation of heparin antagonist VLPs as viable alternatives to protamine.
