Hypothesis
How does prenatal mercury exposure from the World Trade Center disaster affect child development?
Conclusion
The study suggests that prenatal mercury exposure may impact neurodevelopment, but important confounding factors were not included in the analysis.

- Prenatal mercury exposure may affect neurodevelopmental outcomes.
- Breastfeeding and thimerosal exposure were not included in the study's analysis.
- Children born prematurely are at higher risk for lower neurocognitive achievement.

This study looks at how mercury from the World Trade Center disaster might affect how children develop, but it missed some important details.
Methodology
The study assessed psychomotor and intelligence scores in children exposed to mercury during pregnancy.
Potential Biases
Potential bias due to missing important variables like breastfeeding and thimerosal exposure.
Limitations
The study did not account for early thimerosal exposure and feeding methods, which could influence outcomes.
Participant Demographics
Children delivered at term in Lower Manhattan after September 11, 2001.
