[The effect of air pollutants on birth weight in medium-sized towns in the state of São Paulo].
Article in Revista paulista de pediatria : orgao oficial da Sociedade de Pediatria de Sao Paulo, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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 effect of air pollution on birth weight in a medium-sized town in the State of São Paulo, Southeast Brazil.
methodsCross-sectional study using data of live births to mothers residing in São José dos Campos from 2005 to 2009. Data was obtained from the Department of Information and Computing of the Brazilian Unified Health System. Air pollutant data (PM, SO and O) and daily averages of their concentrations were obtained from the Environmental Sanitation & Technology Company. Statistical analysis was performed by linear and logistic regressions using the Excel and STATA v.7 software programs.
resultsMaternal exposure to air pollutants was not associated with low birth weight, with the exception of exposure to SO within the last month of pregnancy (OR=1,25; IC95% 1,00-1,56). Maternal exposure to PM and SO during the last month of pregnancy led to lower weight at birth (0.28 g and 3.15 g, respectively) for each 1mg/m(3) increase in the concentration of these pollutants, but without statistical significance.
conclusionsThis study failed to identify a statistically significant association between the levels of air pollutants and birth weight, with the exception of exposure to SO within the last month of pregnancy.
