Mean number of days that pain made activities difficult, by study occasion, age group, and HRT status. Raw means by study occasion are presented for each age group (65–74, 75–84, and 85+) and HRT continuation group (continuers vs. non-continuers). For each age group, the statistical significance of the HRT continuation group difference in HRQOL change (from ANCOVA analyses; see Table 3) is also shown.
