Iowa study

I found the following comments on your radon study, on another mailing list. 
Would you care to comment on this?

>>> They divided the study subjects
into five parts, ranging from lowest alleged exposure to highest. That makes
sense. And sure enough, they found no significant increase in the lower four
parts, with a significant cancer correlation only in the highest group. 
But that highest "fifth" wasn't a fifth at all; rather it was the top 15
percent. Although it's impossible to tell without looking at data they
didn't present, it appears that if they had fairly made that top category a
full 20 percent, even with their other tricks they still wouldn't have found
statistical significance. <<<<<
