IRR of PD: GTZ-exposed group versus the other antidiabetic drug-exposed group.

Abstract

<p>* Adjusted for matched variables (age, gender, practice, and treatment stage) by conditional Poisson regression analysis.</p><p>** The rate of PD for current users of GTZ was originally divided into exposed <6 months, 6–12 months, and 1–2 years, but these cells were combined to avoid small cells that could compromise anonymity. The crude rates in these three periods were all similar at between 4.36 and 4.94, so there was no suggestion of important variation in that time period.</p><p>IRR of PD: GTZ-exposed group versus the other antidiabetic drug-exposed group.</p
