DOWN'S SYNDROME SCREENING - HOW SHOULD WE ASSESS IT?
Synopisis:
The talk will outline the statistical procedures
underlying the vast majority of methods for screening
for Down's Syndrome. The effectiveness of a screening
programme is usually expressed in terms of an
estimated detection rate. The talk will describe two methods
for this estimation and compare their efficiencies. The use
of the detection rate as a measure of effectiveness has
many problems associated with it, not least that it is often
estimated from a very small sample. These problems will
be described, together with suggestions for overcoming
some of them.
