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
Nerve growth factor (NGF) and its TrkA receptor exert important bioactivities on neuronal cells such as promoting survival and neurite outgrowth. Activated TrkA receptors are not only localized on the cell surface but also in signaling endosomes, and internalized TrkA receptors are important for the mediation of neurite outgrowth. The regulation of the endosomal trafficking of TrkA is so far unknown. Because the endosome-associated GTPase Rab7 coimmunoprecipitated with TrkA, we examined whether the endosomal trafficking of TrkA might be under the control of Rab7. Inhibiting Rab7 by expression of a green fluorescent protein-tagged, dominant-negative Rab7 variant resulted in endosomal accumulation of TrkA and pronounced enhancement of TrkA signaling in response to limited stimulations with NGF, such as increased activation of Erk1/2 (extracellular signal-regulated kinase 1/2), neurite outgrowth, and expression of GAP-43 (growth-associated protein 43). Our studies show that the endosomal GTPase Rab7 controls the endosomal trafficking and neurite outgrowth signaling of TrkA. Because mutations of Rab7 are found in patients suffering from hereditary polyneuropathies, dysfunction of Rab7 might contribute to neurodegenerative conditions by affecting the trafficking of neurotrophins. Moreover, strategies aimed at controlling Rab7 activity might be useful for the treatment of neurodegenerative diseases.
