For each follow-up were calculated four variables:
a) Weight difference was calculated as the weight in each visit minus the baseline weight, expressed in kg
b) Weight ≤ Baseline Weight : If the weight in the visit was lower than the baseline weight
c) Weight loss ≥ 5%: If the relative percentage loss of weight (weight difference/baseline weight) was ≥ 5%
d) Weight loss ≥ 10% : If the relative percentage loss of weight (weight difference/baseline weight) was ≥ 10%
