Usage Notes:

This includes forms from the subsample of OS participants at year 6 that were enrolled in the three clinical centers participating in the WHI Osteoporosis sub study, as height and weight were collected on OS participants at year 6 by design; see table 16.1; on page 16-18b of volume 2.
