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
Fragments of botulinum neurotoxin (BoNT) have been explored as potential targeting moieties and carriers of biomolecules into neurons, although with lower binding and translocation efficiency compared with intact proteins. This study exploits a detoxified recombinant form of full-length BoNT/B (BoTIM/B) fused with core streptavidin (CS-BoTIM/B) for lentiviral targeting to central and autonomic neurons. CS-BoTIM/B underwent an activity-dependent entry into cultured spinal cord neurons. Coupling CS-BoTIM/B to biotinylated lentivirus-encoding green fluorescent protein (GFP) endowed considerable neuron selectivity to the vector as evident from the preferential expression of the reporter in neurons co-cultured with skeletal muscle cells. CS-BoTIM/B-guided lentiviral transduction with the expression of a SNARE protein, SNAP-25 (S25), rendered non-susceptible to proteolysis by three BoNT serotypes, yielded a sizable decrease in cleaved S25 upon exposure of spinal cord neurons to these toxins. This was accompanied by synaptic transmission being spared from blockade by BoNT/A or BoNT/E, reflecting adequate translation and functional competence of recombinant multi-toxin-resistant S25. The augmented neurotropism conveyed on the lentivirus by CS-BoTIM/B was also demonstrated in vivo through enhanced expression of a reporter in intramural ganglionic neurons in the rat trachea, after injection of the targeted GFP-encoding lentivirus. Thus, a novel and realistic prospect for gene therapy of peripheral neuropathies is offered in this study through lentiviral targeting to neurons by CS-BoTIM/B.
