Predictors of tobacco use among pregnant women: a large-scale, retrospective study.

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 investigate the predictors of smoking among pregnant women in Iran, focusing on health literacy and associated socioeconomic factors.
methodsThis retrospective cohort study included 103,042 pregnant women aged 18-45 years who attended healthcare centers affiliated with Mashhad University of Medical Sciences for routine prenatal and postnatal checkups between 2017 and 2020. Data were collected from the Sina Electronic Health Record System (SinaEHR
resultsSmoking prevalence was 0.9%. Women with undergraduate or higher education had significantly lower odds of smoking (OR = 0.36; 95% CI = 0.28-0.47) compared to those with primary education or less. Maternal age was marginally associated with increased smoking risk (OR = 1.01; 95% CI = 1.00-1.03). While unemployment showed an increased crude risk for smoking, this was not significant after adjustment (adjusted OR = 1.02; 95% CI = 0.86-1.21). Strong associations were found between tobacco use and alcohol consumption (OR = 46.3; 95% CI = 24.8-83.4) and opium addiction (OR = 23.4; 95% CI = 14.5-36.3). Chronic disease history also increased smoking odds (OR = 1.51; 95% CI = 1.17-1.92).
conclusionLower education, substance use, and chronic disease are significant predictors of smoking among pregnant women in Iran. Targeted interventions to improve health literacy and address these factors are essential to reduce tobacco use during pregnancy.
