closespecific numbers

what were the specific amount of women used in the study, where did they live, and at did one of the 3-8 weeks prove to be more important or skewed? maybe supplying such facts could help the readers better understand the affects of air pollutants on congenital heart defects and birth defects in general.

The numbers of women are in table 3, the number of cases are in table 4. A map of the study area is shown in Figure 1, we cannot show the homes of the mothers for ethical reasons. We did not examine specific weeks in the 3-8 window of exposure, but narrowing down the exposure window is something we are currently working on.
