BMI: Body Mass Index, CI: Confidence Interval, CRP: C-reactive protein, SD: standard deviation, US: Ultrasound, WC: Waist Circumference.
Continuous variables were expressed using means and standard deviation. Comparisons were performed by T-student test (p value reported in the lower line). Categorical variables were expressed by absolute frequencies, percentages and CI of 95%; comparisons were performed using a Fisher’s test (binary variables) or a Chi-square test (for more than two categories).
All variables included in the Table 1 were evaluated in the analyses. In this table, only statistical significant results are shown.
# Baseline measurements expressed in millimeters as a continuous variable.
¶Measurements at one month and one year of follow up, as a dichotomic variable regarding presence or absence.
