¹HT, hormone therapy.

²β Values (and 95% CIs) from generalized estimating equation models reflect the mean change in percentage body fat from baseline in the intervention group compared with the comparison group during follow-up, stratified by the above baseline characteristics.

³With age as a continuous variable, the interaction term was nearly significant (P = 0.041).

⁴The small numbers of underweight women were combined with normal-weight women for these analyses.
