Conditions
Brief summary
The purpose of this study is to evaluate the long-term effectiveness, safety, and tolerability of FORTEO in a larger, more diverse real world population than studied in clinical trials
Detailed description
Subjects will be followed through a course of FORTEO therapy for up to 24 months and for an additional 24 months after FORTEO treatment is stopped. Subjects may participate in this study for up to 48 months. All aspects of patient care, including diagnostic and therapeutic interventions, will be chosen and conducted at the discretion of the participating study physician according to their clinical judgment and the local standard of medical care.

Physician Criteria for Initiating FORTEO Therapy
Study investigators were provided a questionnaire that was populated with specific criteria they could choose from when they initiated Forteo therapy for their patients. They could have chosen more than one criteria, thus participants could have been counted multiple times. As this was actually a baseline characteristic rather than an outcome measure, data are presented in the baseline characteristic table rather than here.
Time frame: Baseline
Population: Participants are those who took at least one dose of study drug and had reasons documented to initiate Forteo therapy. This is a baseline characteristic; therefore data are presented in the section of Baseline Characteristics.
Treatment Adherence
Treatment adherence is the duration of time participants were on Forteo therapy during the 24-month treatment phase of the study.
Time frame: up to 24 months
Population: Participants who received at least one dose of study drug and had non-missing start/stop date, and did not discontinue study drug more than 3 consecutive months at onetime during treatment phase.
