Calcium+D, Calcium+vitamin D3 group. Control, control group. VFA, visceral fat area.

Δ1=[(mean values wk 4)-(mean values wk 0)]. Δ2=[(mean values wk 8)-(mean values wk 0)]. Δ3=[(mean values wk 12)-(mean values wk 0)].

a The P-value was calculated by independent t-test between means.

b Mean ± standard deviation (all such values).

c n=24 in both groups between wk 0 and wk4; n=23 and 22 for Calcium+D and control groups, respectively, between wk 0 and wk8; n=20 and 19 for Calcium+D and control groups, respectively, between wk 0 and wk12.
