The risk of long-term opioid use among immigrants: a national registry-linkage study.
Article in Scandinavian journal of public health, 2025. 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
aimsWe aimed to investigate the association between being an immigrant and long-term prescription opioid use in Norway in 2010-2019.
methodsNested case-control study. The cases were all persons 18 years of age or older with long-term opioid use - that is, the use of prescription opioids longer than 3 months (
resultsFor the youngest age group, being an immigrant was inversely associated with long-term opioid use (adjusted odds ratio 0.75; 95% confidence interval [0.72-0.77]) compared with being native-born people. For this age group, the odds ratio differed between people born in Africa (0.56 [0.52-0.62]), Central or South America (0.70 [0.62-0.79]), Europe outside the European Union (EU) (0.71 [0.65-0.77]), Asia including Turkey (0.80 [0.77-0.84]) and EU/European Economic Area (EEA) (0.81 [0.77-0.85]). For the middle age group, increased odds were found for immigrants versus natives (1.05 [1.02-1.08]) in particular for those born in North America (1.26 [1.13-1.40]) and the EU/EEA (1.13 [1.09-1.18]). There was no association in the oldest group.
conclusionsCompared with native-born people, immigrants had lower odds of long-term opioid use among younger adults, higher odds among middle-aged and similar odds among older adults.
