1 · What the graph read from it

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.

2 · The registry

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

backgroundWe examined fentanyl use and outcomes among people who inject drugs (PWID) in the urban Pacific Northwest (PNW).

methodsWe conducted secondary analysis of data from the 2022 National HIV Behavioral Surveillance PWID cycle from Seattle, WA and Portland, OR. We calculated proportions of any fentanyl, injection fentanyl, non-injection fentanyl, and street pill use. Next, we compared characteristics, behaviors, and outcomes by any fentanyl use. Finally, we estimated adjusted relative risk (aRR) of overdose outcomes associated with fentanyl use and injecting less associated with type of street pill use.

resultsAmong 830 PWID, 76% reported any fentanyl use, 47% specifically reported injection fentanyl use, 68% specifically reported non-injection fentanyl use, and 66% reported street pill use. Of those who used pills, 94% smoked them. Fentanyl use was crudely associated with age; race; housing; detainment; usual drug injected; injection frequency; syringe service programs, substance treatment, non-fatal overdose, and naloxone (p < 0.05). With adjustment, any fentanyl use (aRR = 3.20, 95% CI 1.58-6.47), injection fentanyl use (aRR = 3.51, 95% CI 1.63-7.58), and non-injection fentanyl use (aRR = 2.29, 95% CI 1.23-4.28) were associated with higher risk of overdose. Participants who smoked street pills were more likely to report injecting less because of pill use (aRR = 1.82, 95% CI 1.24-2.66).

conclusionsFentanyl use was highly prevalent among PWID in the urban PNW. Non-injection fentanyl use was most common and street pills were frequently administered by smoking which was associated with injecting less. All fentanyl use was associated with increased risk for overdose. There is ongoing need for access to naloxone for PWID who use fentanyl.
