Pratrerets. The platelet levels in the 9 and
10-year surveys both revealed greater deficit in
exposed males than in exposed females. Compared
with the unexposed groups the males had 20% less
in 1963 and 12% less in 1964, and the females 7%
less in 1963 and 2% less in 1964 (see Figure 35).
In the scattergrams (Figures 36 through 39) and
the accumulative distribution curves (Figures 24
and 25) the differences are clearly shown.

‘A factorial analysis of variance of unweighted
