Table 1

Summary of creatinine excretion and SM mass calculations.

Patient (35 male with ALS)	Weight (kg)	BMI	24 hr urine creatinine (mg)	Creatinine (mg/kg/day)	SM mass (kg/m^2)
Actual Wt.	105.5	30.8	186	1.76	2.2
I.D. Wt.	79.5	23.2		2.33

SM: skeletal muscle; [1]; I.D. Wt.: ideal body weight [7]. BMI: ; Actual Wt.: actual weight; severe sarcopenia in men:  kg/m².
