Levamisole-Adulterated Cocaine: A Case of Vasculitis and Severe Neutropenia.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Levamisole is an immunomodulatory agent that was formerly used in the United States as a disease-modifying antirheumatic drug (DMARD) for rheumatoid arthritis (RA). More recently, it has become a common adulterant in cocaine. Levamisole exposure has been associated with a broad spectrum of adverse effects, such as neutropenia, agranulocytosis, distinctive skin lesions, vasculitis, arthralgias, and leukoencephalopathy. While the literature on complications related to levamisole exposure is currently sparse, given its increasingly common use as a cutting agent in cocaine, it is likely that they are underreported. Because of this, heightened vigilance among clinicians is warranted. Here we present an unusual case of levamisole toxicity causing both vasculitis with systemic and cutaneous pathology, including severe neutropenia complicated by septic shock.
