Disparities in prevalence of smoking and smoking cessation during pregnancy: a population-based study.
Trial report in BioMed research international, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05343845 (Does Smoking Effect Spinal Anesthesia in Parturient Women? A Randomized-controlled Trial), which is not on this map. Cited by 9 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.

Abstract
objectiveTo examine time trends in prevalence of smoking and smoking cessation during pregnancy by family income, maternal level of education, skin color, and age.
methodsWe conducted three population-based surveys in 2007, 2010, and 2013 with newly delivered mothers living in the municipality of Rio Grande, Southern Brazil. Data were collected using questionnaires administered after delivery in all (two) maternity units in the city, at Dr. Miguel Riet Corrêa Júnior Hospital and at Santa Casa de Misericórdia. Time trends were analyzed using chi-square test for linear trend.
resultsData of 7,572 women showed that the prevalence of smoking before pregnancy decreased from 28% (26.2-29.7) in 2007 to 22% (20.8-24.0) in 2013 (P < 0.001). Prevalence of smoking during pregnancy decreased from 22% (20.4-23.7) in 2007 to 18% (16.6-19.5) in 2013 (P < 0.001). This reduction varied across income ranging from 17% (poorest) to 35% (richest) (P < 0.001). The lower the income, the higher the smoking prevalence during pregnancy. Smoking cessation was more prevalent among women of higher level of education and income.
conclusionsSmoking before and during pregnancy is still highly prevalent and the prevalence of cessation is low pointing to a need to strengthen actions targeting low-income, less educated, black pregnant women.
