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

Introduction: Understanding substance use outcomes across different immigrant populations is critical for informing targeted public health interventions. This systematic review aims to consolidate current findings on the prevalence of substance use among immigrants, focusing on generational differences, to understand substance use trends and their evolution within immigrant communities. Methods: We systematically searched PubMed, PsycINFO, Web of Science, Medline, Cochrane, and Embase for cross-sectional observational studies. We included studies published between 1990 and 2026, examining substance use prevalence among first generation immigrants and second-generation immigrants. Odds ratios were calculated using random-effects models. Heterogeneity was assessed through I Results: From a total of 157,426 screened articles, 51 studies were included in the final analysis, covering 4,933,781 individuals from more than 9 countries. For alcohol, the OR was 1.68 (95% CI: 1.38; 2.04) for consumption, 2.10 (95% CI: 1.68; 2.64) for dependence and 2.08 (95% CI: 1.83; 2.37) for abuse. Regarding drug use, overall OR was 2.18 (95% CI: 1.81; 2.63) for consumption, 4.32 (95% CI: 3.48; 5.37) for abuse and 4.21 (95% CI: 3.19; 5.55) for dependence. OR for cannabis use was 3.8 (95% CI: 2.12; 6.92) whereas for tobacco use, no significant difference was found (OR 1.61; 95% CI: 0.98; 2.64). Conclusion: The findings highlight generational differences in substance use outcomes, with second-generation individuals often displaying higher usage rates compared to the first-generation. These results underscore the need for culturally tailored intervention and prevention strategies.
