MISSOURI DIOXIN HEALTH STUDIES - PROGRESS REPORT - OCTOBER 16, 1983 CIRCULATE: W. J. McCarville - G3WG D. R. Bishop - F3EE Fannie Price - G2WA Comments from W. R. Gaffey - 2/24/84 High risk group is self-reported. Low risk group is self-reported. Sometimes laboratory norms were used instead of control group values. Note page 36 - more elevated heptas in the low risk grohp - more lymph nodes in the low risk group. It seems to me that most of the conclusions are more or less independent of the data. For example, had there been positive findings, the report would certainly recommend preventing human exposures. In fact, there were no positive findings, and the report still recommended preventing human exposure. I have no criticism of the specific statistical techniques used. G.
