Fentanyl Polysubstance Use Patterns and Their Associations With Hepatitis C Virus, Skin and Soft Tissue Infections, and Non-Fatal Overdose Among People Who Inject Drugs in New York City.
Article in Drug and alcohol review, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
introductionFentanyl's euphoric effects and short half-life may increase infectious disease transmission risks through frequent injecting and syringe sharing. We examined fentanyl polysubstance use (PSU) patterns and associations with hepatitis C virus (HCV), skin and soft tissue infections (SSTI), and non-fatal overdose among people who inject drugs (PWID) in New York City.
methodsWe recruited 495 PWID between October 2021 and July 2024. Participants were tested for HCV antibody and underwent urine toxicology screenings using the Premier Biotech 13-panel BioCup.
resultsFentanyl was identified in 83.6% of the sample; however, only 23.0% self-reported recent intentional fentanyl use. The most common fentanyl PSU combinations were fentanyl with methadone (67.9%), opiates (66.9%), cocaine (65.9%), cannabis (45.4%), xylazine (36.7%), heroin (35.5%), benzodiazepines (32.5%) and alcohol (29.3%). Compared to no fentanyl use, intentional fentanyl use was associated with HCV antibody seropositivity (aOR 3.44, 95% CI 1.75, 6.93), SSTIs (aOR 4.75, 1.66, 17.20) and non-fatal overdose (aOR 2.35, 1.15, 5.00). Co-use of fentanyl with opiates (aOR 2.08, 1.16, 3.82), cocaine (aOR 2.71, 1.52, 4.97), heroin (aOR 2.06, 1.11, 3.91), benzodiazepines (aOR 2.91, 1.55, 5.63) and alcohol (aOR 3.27, 1.72, 6.37) were associated with HCV. Co-use of fentanyl with benzodiazepines (aOR 2.08, 1.04, 4.34) and alcohol (aOR 2.57, 1.29, 5.37) were associated with non-fatal overdose. DISCUSSION AND
conclusionsIn addition to overdose, when combined with other psychoactive substances, fentanyl PSU is associated with a higher prevalence of infectious diseases. This underscores the need for tailored medication dosing for opioid use disorder and expanding access to syringe service programs and medical care for PWID in the fentanyl era.
