BUN—blood urea nitrogen; MIS—malnutrition inflammation score; PEW—protein energy wasting; ISRNM—International Society of Renal Nutrition and Metabolism criteria. Continuous variables are expressed as mean ± SD or median with interquartile range in case of non-normally distributed data, and categorical variables are expressed as a percentage. p < 0.05 was considered statistically significant.
