Morphine exposure during HIV encephalitis in SCID mice.
Article in Neurochemical research, 2012. 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
HIV encephalitis (HIVE) is often complicated by opiate abuse. Based on human pathological, animal and in vitro studies, opiates are thought to exacerbate HIVE. To test this hypothesis we exposed 10 week old SCID mice with HIVE to morphine and examined histopathological parameters. Mice inoculated intracerebrally with either HIV-infected or uninfected (control mice) human macrophages were immediately implanted subcutaneously with pellets containing saline, morphine or morphine plus naltrexone. They were sacrificed after 10 days. Immunostaining for astrocytes (GFAP), mouse mononuclear phagocytes (CD45) and neuronal dendrites (MAP2) was analyzed by densitometry. HIVE mice exposed to either saline, morphine or morphine plus naltrexone also had brain sections counted for HIV+ human macrophages. Typical HIVE pathology was present, consistent with previously published studies. Surprisingly, there were no effects on astrogliosis, microgliosis and MAP2 decreases in the HIVE, morphine treated group. There was also no effect of morphine exposure on numbers of p24+ human macrophages. These results emphasize the complexities of modeling opiate effects in HIVE and the potential significance of opiate abuse on HIVE in humans.
