ERICA: smoking is associated with more severe asthma in Brazilian adolescents.
Article in Jornal de pediatria. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
objectiveTo investigate the association between smoking and asthma, and possible associated factors in Brazilian adolescents.
methodsA cross-sectional, national, school-based study with adolescents aged 12-17 years, participants in the Study of Cardiovascular Risks in Adolescents (Estudo de Riscos Cardiovasculares em Adolescentes - ERICA). A total of 66,394 participants answered a self-administered questionnaire with questions about asthma, smoking, lifestyle and sociodemographic variables. Bivariate analysis between Current Asthma (CA) and Severe Asthma (SA) and the other study variables were performed using Chi-squared. Then, the crude and adjusted Prevalence Ratios (PR), and respective 95% Confidence Intervals (95% CI) of current asthma/severe asthma and smoking variables, corrected for sociodemographic and lifestyle variables, were estimated using generalized linear models with Poisson regression, logit link, and robust variance.
resultsThe prevalence of current asthma and severe asthma were significantly higher in adolescents who were exposed to: experimentation (current asthma: PR=1.78, 95% CI: 1.51-2.09; severe asthma: PR=2.01; 95% CI: 1.35-2.98); current smoking (current asthma: PR=2.08, 95% CI: 1.65-2.64; severe asthma: PR=2.29; 95% CI: 1.38-3.82); regular smoking (current asthma: PR=2.25, 95% CI: 1.64-3.07; severe asthma: PR: 2.41; 95% CI: 1.23-4.73); and passive smoking (current asthma: PR=1.47, 95% CI: 1.27-1.67; severe asthma: PR=1.66; 95% CI: 1.19-2.32); these associations remained significant after adjustment.
conclusionsAsthma and smoking were significantly associated in Brazilian adolescents, regardless of the sociodemographic and lifestyle factors, notably in those with more severe disease.
