BF = Body fat, FFM = Fat-free mass, FMI = fat mass index, FFMI = fat-free mass index; Different superscript between groups means the significant difference between genotypes (p < 0.05).
Superscript a, b, c follow the order of lower to higher score (a < b < c).
*
= Statistically significant difference (p < 0.05) from the variable results of genotype of normal adults
