HIV transactivator of transcription enhances methamphetamine-induced Parkinson's-like behavior in the rats.
Article in Neuroreport, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
Abuse of methamphetamine (MA) increases the risk of infection of HIV-1, induces considerable neurotoxicity in several brain regions, and impairs the motor and cognitive function in individuals. HIV-1 transactivator of transcription (Tat) has also shown the potent capability to induce neuronal death and impaired brain function. The present study aims to study the synergistic effect of MA and Tat on cytokine synthesis in substantia nigra, striatal dopamine content, and behavioral performance in the rats. Although increased expression of cytokines (interleukin-1β and tumor necrosis factor-α) was observed in the substantia nigra in the rats receiving either MA or Tat alone, a combination of MA and Tat induced a larger and more sustained upregulation of cytokines. In the rats receiving either MA or Tat alone, significant loss in striatal dopamine content was found, which was further exacerbated in the rats receiving both MA and Tat. In the rats receiving either MA or Tat alone, significantly lower performance in the rotarod test and open-field test was observed, whereas the rats receiving both MA and Tat showed more sustained behavioral impairments. These results suggested that Tat protein synergized with MA to induce central neuroinflammation and impair the dopaminergic transmission, thus leading to sustained Parkinson's-like behavior.
