Fat-free mass % (value calculated using impedance)

Imputation and derivation

Derivation

variable: weight (table[s]: this dataset)
variable: ffmass_I (table[s]: this dataset)
variable: dropped_I (table[s]: this dataset)

gen ffmasspc_I=100*(ffmass_I/weight) if weight~=. & ffmass_I~=.
<remove inconsistent data from combined data:>
foreach var in fatmass_I fatmasspc_I ffmass_I ffmasspc_I {
replace `var'=. if dropped_I==1
}
