Extra Journal Club: Cd exposure and neurodevelopment

I’m sure reading a lot lately. That is good. This week, I’m filling in for the PBF journal club, too, and today we’ll be discussing Ciesielski et al’s paper Cadmium Exposure and Neurodevelopmental Outcomes in U.S. Children, which uses 6 years of NHANES data to weigh the evidence that low levels of cadmium cause learning disabilities in children.

All the data is available on the CDC’s website, so I thought I’d take a look at it. Here is an interesting little plot that popped out: prevalence of parent-reported learning disabilities in 6-15 year olds as a function of income-to-poverty-line ratio.


Would you have expected that?
