Lynne Kiesling On Floyd Landis

Some simple statistics come to the rescue of Tour De France winner Floyd Landis, whose win is at the moment under a cloud of suspicion:

His ratio of testosterone/epitestosterone was high; they test for this because if you are testosterone doping (i.e., through patches etc.) it will mess up your ratio, which for most folks is normally around 1:1 but can be higher for endurance athletes. This year the UCI has changed the trigger ratio from 6:1 to 4:1.

Problem is, it's a ratio (and you economists out there know the problem of drawing inferences about X and Y separately by looking at the ratio X/Y). According to the reports I've read this afternoon, Landis' ratio was high not because of high testosterone; his testosterone was at normal levels, but his epitestosterone levels were extremely low. Epitestosterone cannot be turned into testosterone in the body. So it's possible that the result is from too low a Y and not a too high X.

How can this be? Two of the things that can affect epitestosterone are alcohol and cortisone. We know that Landis had a beer the night before the stage because he was so upset at his bonking on that stage. We also know that Landis is legally taking cortisone shots for his half-dead hip.

Lets hope this is true and can be demonstrated.

Demonstrated to who? This is the same crap lance Armstrong put up with for years.

Get real! Everybody inside cycling knows Landis has doped. Period. As most other do as well. He got caught. Probably took to big a risk, since it was his last chance. And time-wise it was a perfect match. Only not test-wise ;-)
