Question #1----How many devide %S by ploidy status?
Answer: 8/9 (88%)
Question #2----How do they define there cut points?
Answer: all use their own distributions
Answer: 7/9 (78%) use tertiles
2/9 (22%) use median or other methods
Question #3------What are the cut points used.
Answer: For those who use tertiles 5 of 7 gave values. The range
of intermediate % S values for diploid was 3 to 7 and the intermediate %S
for aneuploid was 6 to 17. The low and high values were below or above the
intermediate ranges.
For those who used median values and gave the value, it
was 6.5%. The other labs that answered the question did not give any
values.
I hope that this small data set gives some information for thought.
However, it would have been nice to have more participation.
