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
backgroundAlcohol consumption during pregnancy poses serious risks to maternal and fetal health, making it a public health concern. This study sheds light on the sociodemographic disparities linked to alcohol use among pregnant women in Brazilian capital cities, highlighting vulnerable groups and regional variations. These findings underscore the urgent need to develop tailored preventive strategies to protect maternal and child health. ■ Any alcohol consumption during pregnancy: prevalence of 11.5%. ■ Excessive alcohol consumption during pregnancy: prevalence of 3.0%. ■ Risk factors: older age, low education, and Indigenous ethnicity. ■ Protective factors: being married and living in Northern Brazil.
objectiveTo analyze the prevalence and factors associated with alcohol consumption among pregnant women.
methodsThis cross-sectional study examined pregnant women living in Brazilian capitals using information collected by the Noncommunicable Chronic Disease Risk Factor Surveillance System (Vigitel) between 2006 and 2021. This study calculated the prevalence of both excessive and any amount of alcohol consumption by pregnant women and their associations with sociodemographic variables. Multivariate analysis was performed with prevalence ratios based on Poisson crude and adjusted regressions; the threshold for statistical significance was set at p<0.05.
resultsThe sample comprised 4,734 pregnant women. The prevalence of any amount of alcohol consumption was 11.5% (95%CI = 9.8-13.6), and that of excessive consumption was 3.0% (95%CI = 2.1-4.2); both remained stable throughout the analyzed period. Being 35-54 years old and having low educational attainment were the main factors associated with both consumption patterns. Being Indigenous was highly associated only with excessive alcohol consumption, whereas being legally married and living in Northern Brazil were protective factors.
conclusionThese findings emphasize the need for focused preventive strategies targeting the most vulnerable groups to mitigate alcohol consumption and its associated risks during pregnancy.
