Differential antinociceptive effects of buprenorphine and methadone in the presence of HIV-gp120.
Article in Drug and alcohol dependence, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
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
backgroundWe showed recently that elevated brain levels of the chemokine stromal cell-derived growth factor-1α (SDF-1α/CXCL12, a ligand for the human immunodeficiency virus [HIV] co-receptor CXCR4) diminish the antinociceptive effect of morphine, but failed to influence buprenorphine-induced antinociception.
aimsBecause the HIV-1 coat protein, glycoprotein 120 (gp120) T-tropic strain, binds to the same receptor as SDF-1α/CXCL12, the present experiments were designed to investigate the consequence of administering gp120 to rat brain on buprenorphine-induced antinociception in the 54°C hot plate test. For comparative purposes, the effect of gp120 on an equi-antinociceptive dose of methadone was also examined.
methodsA sterilized stainless-steel C313G guide cannula was implanted into the periaqueductal grey (PAG), a brain region critical for the processing of pain signals, and a primary site of action of many analgesics. Rats were pretreated with gp120, administered into the PAG.
resultsThe subsequent antinociception associated with methadone was diminished whereas buprenorphine-induced antinociception was unaffected. Buprenorphine thus appears to be a more effective analgesic than methadone in the presence of gp120 in the brain, a condition that is associated with HIV-related pain and infection.
