Notes: FM = fat mass; FFM = fat-free mass; IGF1 = insulin-like growth factor 1; RMR = resting metabolic rate; TDEE = total daily energy expenditure; T3 = triiodothyronine; T4 = thyroxine. For the model FI34 = b 0 + b 1·age + b 2·sex + b 3·FM + b 4·FFM + b 5·TDEE + b 6·RMR + b 7·T3 + b 8·T4 + b 9·IGF1, adjusted R 2 = .339 (p = 6.27 × 10− 8) with 99 df. b is the regression coefficient and SE (b) is the standard error of the coefficient.
