Statistical Analysis
Data were analyzed using IBM-SPSS Statistics 20 software. The comparison
between two groups were done by Mann-Whitney U-test or t-Student, or
chi-square test where appropriate. Comparisons among several groups were
made using Kruskal-Wallis test or ANOVA, as appropriate. Spearman’s or
Pearson’s test were used for correlations between cytokine/adipokines
and clinical characteristics. Multiple linear regressions were performed
for the analysis of predictors. A p-value ≤ 0.05 was considered
statistically significant.
