Zip codes for the home addresses of the patients with low (<5.5 ng/mL) and high (>25.7 ng/mL) serum folate levels were compared. Only the zip codes with at least five members of one of the groups were included. The distribution of patients in the various zip codes, and by inference, economic status, were not meaningfully or statistically different. The data was analyzed for goodness of fit and p value was 0.86.
