* Only participants agreeing to enroll after first being approached with the randomized study to either a control or clinic-based exercise group were randomized. Participants in the home-based group were directly assigned to this group without being randomized, as they were individuals who refused the randomized study initially, but were offered the chance to still participate by being allowed to directly enroll in a home-based program.

† For purposes of analyses, the clinic-based and home-based group were combined into a single intervention comparison group.
