Prevalence of Cigarette Smoking and its Related Factors among Students in Iran: A Meta-Analysis.
Review in Tanaffos, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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: Smoking is a preventable cause of morbidity and mortality with an increasing prevalence in developing countries. The present systematic review and meta-analysis aimed to estimate the prevalence of smoking among college and high school students in Iran. Materials and Methods: Databases of Scopus, PubMed, Web of Science, Google Scholar, SID, and MagIran were searched with no time limitation. Observational studies published in Persian or English were included in the analysis. Time frame of the searches was from inception until 1 January 2021. The data was analyzed using random effects model, subgroup analysis, and meta-regression analysis. Heterogeneity among studies was examined using Cochran's Q test and I Results: A total of 63 articles with a sample size of 58742 were analyzed. The pooled smoking prevalence was found to be 13.56% (95% CI: 11.65-15.47). There was a significant increase in the prevalence of smoking among female students between 1998 and 2020. Regions 1 of Iran had the highest prevalence rates of smoking (Provinces of Alborz, Tehran, Qazvin, Mazandaran, Semnan, Golestan, and Qom). Smoking was more prevalent among college students (15.62%, 95% CI: 13.14-18.10) than in high school students (9.77%, 95% CI: 7.19-12.35). Conclusion: Given the relatively high prevalence of smoking among Iranian college and high school students, it is necessary to inform them about the harmful effects of smoking through training programs.
