^*Estimates weighted according to sampling design (see Methods).

^†Subjects who were unable to perform the walk (N = 1) and chair stand test (N = 22) were coded as missing.

^‡Composite physical function score (walk plus chair; see Methods). Higher scores indicate better physical function.

Bolded correlation coefficients are significant at P < .05. Significance levels are displayed in the grey highlighted areas below the diagonal.

Abbreviations: total testosterone (TT), free testosterone (FT), total estradiol (E2), free estradiol (FE2), appendicular lean mass (ALM), and fat mass (FM).
