Predictions of scaled weight based on lean body mass, fat-free mass,13 modified fat-free mass,16,17 ideal body weight, and pharmacokinetic (PK) mass14,15 are presented for female and male individuals of various heights over a range of total body weights. At a total body weight of 90 kg for the female and 130 kg for the male, the lean body mass predictions start to decrease for increasing total body weight represented with a dashed blue line. The ideal body weight remains the same regardless of total body weight (red line). PK mass remains the same regardless of height and gender (black line).
