  1. P values were analyzed by using Wilcoxon signed rank test to evaluate changes.
  2. WC = WC_2 - WC_1, WC_1 = waist circumference before treatment, WC_2 = waist circumference after treatment.
  3. WC Max = WC MAX_2 - WC MAX_1, WC MAX_1 = maximum waist circumference before treatment, WC MAX_2 = maximum waist circumference after treatment.
  4. SFA = SFA_2 - SFA_1, SFA_1 = superficial fat area before treatment, SFA_2 = superficial fat area after treatment.
  5. VFA = VFA_2 - VFA_1, VFA_1 = visceral fat area before treatment, VFA_2 = visceral fat area after treatment.
  6. TFA = TFA_2 - TFA_1, TFA_1 = total fat area before treatment, TFA_2 = total fat area after treatment.
  7. SD standard deviation, Min minimum, Max maximum.
