Note: *: P < 0.05; **: P < 0.01.
Δ: percentage change, equals (Follow-up - Baseline)/Baseline * 100.
BMI: body mass index; TrF: percentage change in trunk fat; TrL: percentage change in trunk lean; PTrF: percentage change in percentage of trunk fat.
Correlation coefficients were calculated by Pearson correlation, using pooled data from the placebo, Ca-only, and Ca + D groups.
