Drug positivity, co-detection patterns, and demographic predictors in patients seeking substance use disorder treatment, United States, 2023.
Article in Addictive behaviors, 2026. 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
objectiveTo examine drug positivity, co-detection patterns, and demographic associations across 14 drug categories in patients seeking substance use disorder (SUD) treatment.
methodsThis cross-sectional study analyzed 2023 urine drug testing data from Quest Diagnostics. Included were patients aged ≥ 15 years with a valid first urine drug test result ordered by SUD treatment providers. Tests screened for 14 drug categories, including fentanyl, heroin (6-acetylmorphine only), prescription opioids, stimulants, benzodiazepines, and others. Outcomes included drug positivity, paired drug co-detection, and associations with age, sex, insurance type, and geographic region using multivariable logistic regression.
resultsAmong 99,224 patients, most were aged 35 - 54 years (46.9%), male (62.6%), on Medicaid (48.2%) or private insurance (46.5%), and resided in the Northeast (56.3%). Buprenorphine (24.5%) and fentanyl (17.5%) had the highest positivity rates, with fentanyl frequently co-detected with other substances. Patients aged ≥ 25 years had higher odds of drug positivity (adjusted odds ratio [AOR] range: 1.3 - 9.8), except for fentanyl, methamphetamine, and amphetamine. Males had higher odds of fentanyl (AOR, 1.1) and cocaine (AOR, 1.1) positivity but lower odds for most other drugs. Medicaid beneficiaries had increased odds for multiple substances, including methadone (AOR, 3.4) and buprenorphine (AOR, 1.7), versus those with private insurance. Regional variation was notable, with higher odds for buprenorphine in the Midwest and South, but lower odds for methadone compared to the Northeast.
conclusionsThis study highlights variations in substance presence and co-detection across 14 drug categories in SUD treatment patients, underscoring the need for tailored prevention and treatment strategies.
