Peer Influence and Use of Electronic Cigarettes among Adolescents and Young Adults: A Meta-Analysis of Prospective Studies.
Synthesis in Asian Pacific journal of cancer prevention : APJCP, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 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
objectiveTo examine the association between peer use and individual use of EC among adolescents and young adults.
methodsWe performed the search strategy on PubMed, EMBASE, and Cochrane. We selected prospective studies reporting adjusted odds ratio (aOR)/relative risk (aRR) with a 95% confidence interval (CI) and conducted a random-effects meta-analysis.
resultEleven prospective studies were included, involving 32,014 participants in the quantitative analysis. Meta-analysis results showed a significant association between EC use by friends and increased odds of individual EC use (aOR = 1.79, 95% CI 1.43 to 2.25; I2 = 88.2% for ever use; aOR = 2.14, 95% CI 1.52 to 3.01; I2 = 88.5% for current use). In the subgroup meta-analysis of outcomes, having friends who used EC significantly increased the odds of ever- and current EC use. Similar findings were found in the subgroup meta-analyses by age group, region, sample size, study methodological quality, and follow-up time.
conclusionThis study revealed a positive association between individual EC use and friends' use, especially among those under 18 years, suggesting targeting peer networks to curb the EC epidemic.
