You'll read all about the "Ozone causes asthma" claim in the next couple of weeks as all the Usual Suspects begin to print/distribute/wail-and-gnash-teeth over the results.
Too bad that it follows the usual (EPA)-funded protocol: 1) invent a problem, 2) spend lotsalotsa OPM on the "solution." Exactly the formula for creating TSA, GunRunner-Fast/Furious, and the Department of Education, not to mention a number of D of Defense programs and Global "Warming."

...Now if you look at the table entries under “8-hour ozone level (ppb)”, you’ll notice that, with the exception of the odds ratio for “≥100 vs. <50″, all the odds ratios are statistically insignificant (i.e., confidence intervals bound the no-effect level of 1.0 and the p-values all exceed 0.05).
It's damned hard to make up a story which is internally consistent. Ask any cop.
