Associations Between Self-Reported Cocaine Use Patterns and Cocaine and Its Metabolites in Hair: Implications for Clinical and Forensic Practices.
Article in Drug testing and analysis, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
In forensic toxicology, it has been debated if hair testing allows an estimation of the intensity of cocaine use-an assumption that may have risen because self-reports in a forensic setting are of uncertain validity per se. We therefore investigated the relationship between self-reported cocaine use and cocaine hair concentrations (including its main metabolites benzoylecgonine and norcocaine) in chronic cocaine users voluntary participating in psychiatric study settings. Additionally, we tested whether hair testing can distinguish between individuals with and without a diagnosis of cocaine dependency. Cocaine users (N = 195) from three independent experimental studies reported their average powder cocaine consumption in g/week over the last 3-4 months in an interview and provided a 3- to 4-cm hair sample assayed with liquid chromatography tandem-mass spectrometry. Moreover, study participants were assessed with the Structured Clinical Interview (SCID-IV) for psychiatric diagnoses. Using linear regression models, we found a robust correlation between cocaine
