Table 4. Estimated relative prescription rate (Rpr) of the studied drug for participating physicians versus controls.
Time frame | Number of packages | DDD* | ||
---|---|---|---|---|
Rpr** (95% CI) | p-Value | Rpr (95% CI) | p-Value | |
t0 | 1.04 (1.03–1.05) | <0.001 | 1.04 (1.03–1.04) | <0.001 |
t1 | 1.08 (1.07–1.10) | <0.001 | 1.07 (1.06–1.09) | <0.001 |
t2 | 1.07 (1.05–1.09) | <0.001 | 1.06 (1.04–1.08) | <0.001 |
Model for t0 adjusted for overall prescription rate; models for t1 and t2 adjusted for overall prescription rate and prescription rate of studied drug at t0.
*Defined daily dose (DDD) of the drug studied in the non-interventional post-marketing study.
**Relative rate; n = 2,354 groups.
