Analysis data was done using the multivariate logistic regression analysis (adopted factors: diabetes mellitus, age, systolic blood pressure, eGFR, overweight, obesity, fasting glucose and indoxyl sulfate).

eGFR: estimated glomerular filtration rate.

*p < 0.05 was considered statistically significant.
