Relationship of Different Study Drugs Exposure with Recurrence of Urolithiasis in Conditional Logistic Regression Models.

Abbreviation: cDDDs = Cumulative defined daily dose.1 Adjusting for all variables listed in Table 1 except age and gender.2 A 180-day drug exposure window was defined as the use of study drug days within 180 days from the date of first pharmacy claim after 180-day complete treatment period.3 As described in the method section, we matched case and control based on their age, gender and date of first pharmacy claim after the 180-day complete treatment period. After matching, we assigned the date of stone recurrence in each case to his/her matched control at the end of follow-up.Relationship of Different Study Drugs Exposure with Recurrence of Urolithiasis in Conditional Logistic Regression Models.
