^aA UTI episode includes the 14-day period after initial visit date of the UTI. One patient may have multiple UTI episodes, and therefore the total number of UTI episodes (40 603) is greater than the total number of patients (28 678) in the study.

^bStudy period 1 includes 2002 through 2004. Study period 2 includes 2005 to 2007.

^cThe P value is the difference in proportion of urine test use between study period 1 and study period 2 using the χ² test.
