Prevalence of opium use and use disorder in the Iranian population: A systematic review and meta-analysis.
Synthesis in Addiction (Abingdon, England), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper, 1 of them a synthesis that pooled 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.
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
BACKGROUND AND
aimsDespite historical and cultural roots, there is limited comprehensive data on the prevalence of opium use and use disorder across the Iranian population. We systematically reviewed the prevalence and trends of opium use and use disorder in Iran.
methodSystematic review and meta-analysis adhering to PRISMA guidelines, including studies from 1990 to 2023 across the Iranian general population, university students, the young population and specific populations. Measurements included the prevalence of opium use and use disorder by sex, time indicators (lifetime, last 12 months, last month/current, current daily or almost daily), study year and population subgroups.
resultsA total of 115 studies were included. Pooled prevalence of last 12-month opium use among the general population was 8.4% [95% confidence interval (CI) = 5.1-12.6%, studies = 6, n = 9302, I
conclusionsDespite global shifts to harder opioids, opium use continues to have a very high prevalence among the Iranian general population. While the overall prevalence appears stable, younger generations have shown a declining use pattern.
