Construction of metabolically biotinylated adenovirus with deleted fiber knob as targeting vector.
Article in Virology journal, 2010. 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
Gene delivery vectors based on adenovirus, particularly human adenovirus serotype 5 (hAd5) have great potential for the treatment of variety of diseases. However, the tropism of hAd5 needs to be modified to achieve tissue- or cell- specific therapies for the successful application of this vector system to clinic. Here, we modified hAd5 tropism by replacing the fiber knob which contains the coxsackievirus B and adenovirus receptor (CAR)-binding sites with a biotin acceptor peptide, a truncated form of Propionibacterium shermanii 1.3 S transcarboxylase domain (PSTCD), to enable metabolically biotinylation of the virus. We demonstrate here that the new adenovirus no longer shows CAR-dependent cell uptake and transduction. When metabolically biotinylated and avidin-coated, it forms a nano-complex that can be retargeted to distinct cells using biotinylated antibodies. This vector may prove useful in the path towards achieving targeted gene delivery.
