Naïve Patients cohort

This cohort was a subgroup of the All Patients cohort and consisted of those patients initiating osteoporosis therapy during the observation period that had no previous osteoporosis therapy recorded. Those who had received any osteoporosis therapy in the 12 months before 2010 were excluded from this cohort. Each patient’s prescription window was defined as for women of the All Patients cohort.

In the All Patients and Naïve Patients cohorts, data were analyzed in a patient-centric manner, in which persistence with osteoporosis medication was measured irrespective of changes in drug class.
