1 · What the graph read from 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.

2 · The registry

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

purposeLow birth weight has been associated with increased risks of mortality and/or morbidity in childhood and adulthood. Epidemiological studies suggest that maternal exposure to air pollution, especially particulate matter during pregnancy, is associated with an increased risk of delivering a low birth weight infant. The aim of this study is to explore the association between exposure to particulate matter (PM10) during pregnancy and term low birth weight (LBW: birth weight <2,500 g and gestation age ≥ 37 weeks).

methodsBirth data from the Allegheny County Health Department, Pittsburgh, PA, USA and PM10 air data generated with inverse-distance interpolation by RAND's Center for Population Health and Health Disparities, were obtained. The study population consisted of all term singleton live births (gestational age ≥ 37 weeks) born between January 1, 1994 to December 31, 2000. Infants with birth weight <2,500 g were classified as LBW. Logistic regression with robust variance estimation was performed to estimate the odds ratios of LBW per inter-quartile range increase in PM10.

resultsThe results showed that the odds ratios of term LBW per inter-quartile range increase in PM10 were 1.13 (95% CI: 1.02-1.25) during the first trimester and 1.10 (95% CI: 1.00-1.22) during the second trimester after adjustment for other important covariates, respectively.

conclusionThe findings of the study support the hypothesis that exposure to PM10 is associated with increased levels of term LBW. Further studies are warranted to corroborate these findings.
