SD= standard deviation, RPD=relative percent difference,

= square root transformed version of the variable was used;

=indicates the reference group, TFA= total fat area, VFA= visceral fat area, SFA= subcutaneous fat area, IFA= intraperitoneal fat area, RFA= retroperitoneal fat area and VFR= visceral fat ratio VFA/SFA.

= significant (p < 0.05) and B) ANOVA using the Duncan test for identifying significant differences of mean fat compartment measures between stages.
