I've read some of the actual studies you've quoted (and others), and they seem to indicate that infants that sleep on their backs fair slightly better in statistics. Some also blame heavier blankets and "bumper pads" (the pads that wrap around the bars at the base of the mattress).
As I mentioned elsewhere, my understanding is that it's merely a recommendation based on statistics with no direct correlation.
My babies went on their backs, because even a %.001 difference is enough for me to play the game, seeing as I don't know what I'd do if one of them passed away.

"a recommendation based on statistics" usually means there is a correlation. I think you mean that it may not imply causation, which is true of course.
