Data represented as mean ± standard deviation and number (%).
The p value by ANOVA test (continuous variables) or χ2 test (categorical variables).
D1, less 1 year; D2, 1–5 years; D3, above 5 years; BMI, body mass index; eGFR, estimated glomerular filtration rate; CCI, Charlson comorbidity index; SGA, subjective global assessment; PEW, protein-energy wasting; ANOVA, analysis of variance.
*There exists the significant difference between D1 and D3 groups.
