Table 3 Standardised linear effect of free androgen index (FAI) on lean mass index (LMI), upper body lean mass index (UBLMI), lower body lean mass index (LBLMI) or combined handgrip strength in 18–40-year-old females (n = 716).
From: Total testosterone is not associated with lean mass or handgrip strength in pre-menopausal females
