The association of air pollution with body mass index: evidence from Hong Kong's "Children of 1997" birth cohort.
Article in International journal of obesity (2005), 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 16 papers, 5 of them syntheses 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
backgroundChild overweight and obesity have increased substantially in many countries. Physical and psychological effects of childhood obesity endure throughout adulthood. Much attention has been paid to energy intake and expenditure in childhood adiposity, but less to environmental factors, such as outdoor air quality. Here we assessed prospectively the association of exposure to air pollution with body mass index (BMI) in late childhood and early adolescence.
methodsWe assessed the association of air pollutants (particulate matter with a diameter of 10 µm or less (PM
resultsAssociations were sex-specific based on better model fit when including sex interaction terms. Among boys, higher SO
conclusionsThese findings of air pollutant- and sex-specific associations with adiposity should give impetus to the investigation of their physiological effects, possibly operating as endocrine disruptors or via mitochondria, so as to protect the next generation of boys.
