IHCIS; Early 5ARI Initiation
Participants from the Integrated Health Care Information Solutions (IHCIS), a nationally representative managed care database that represents over 30 health plans and more than 25 million lives. Early 5ARI Initiation was defined as participants who started on a 5-alpha-reductase inhibitor (5ARI \[dutasteride and finasteride\]) within 30 days of an alpha-blocker (AB \[doxazosin, prazosin, tamsulosin, terazosin, and alfuzosin\]).
IHCIS; Late 5ARI Initiation
Participants from the IHCIS, a nationally representative managed care database that represents over 30 health plans and more than 25 million lives. Late 5ARI Initiation was defined as participants who started on a 5ARI (dutasteride and finasteride) \> 30 days after an AB (doxazosin, prazosin, tamsulosin, terazosin, and alfuzosin).
PharMetrics; Early 5ARI Initiation
Participants from PharMetrics, a database containing data from over 90 different managed healthcare plans, encompassing over 60 million lives. Early 5ARI Initiation was defined as participants who started on a 5ARI (dutasteride and finasteride) within 30 days of an AB (doxazosin, prazosin, tamsulosin, terazosin, and alfuzosin).
PharMetrics; Late 5ARI Initiation
Participants from PharMetrics, a database containing data from over 90 different managed healthcare plans, encompassing over 60 million lives.
