*All data based on Risk Assessment Questionnaire (RAQ) inputs; SD = standard deviation; BMD = bone mineral density; NA = not applicable.
^†Based on analysis of variance or chi-square tests.
^†Percentage calculated as the number of age-eligible patients who completed the RAQ divided by the number of age-eligible patients with at least 1 physician visit. All percentages in subsequent rows calculated with respect to the number of age-eligible patients who completed the RAQ at the particular site.
^†The lower limit of the range is 0 because s ome patients completed the RAQ during a `non-visit’ (i.e., visited the practice but did not see a physician or nurse).
^†At-risk for osteoporosis is defined as 1 major or 2 minor risk factors according to clinical practice guidelines [30].
