Cocaine-Induced Dermatomucositis: Clarifying Diagnostic Controversies and Introducing IgG4 Positivity as a New Histopathological Feature.
Review in Dermatology and therapy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Cocaine-induced dermatomucositis is a recently described clinical entity with significant controversy regarding its diagnostic criteria and pathophysiology. While previous reports have identified a distinct pattern of chronic inflammatory mucocutaneous lesions in people who use cocaine, the absence of standardized diagnostic markers has led to inconsistencies in classification. This case series aims to clarify and unify the defining characteristics of cocaine-induced dermatomucositis by analyzing its clinical presentations, histopathologic findings, and immunologic features. Notably, we introduce immunoglobulin G4 (IgG4) positivity as a newly observed characteristic, challenging previous assumptions that excluded IgG4-related immune responses from its pathogenesis. By consolidating clinical and histologic patterns, this study contributes to the ongoing effort to establish cocaine-induced dermatomucositis as a distinct and recognizable disorder, paving the way for improved diagnosis and management.
