Association between kidney function, nutritional status and anthropometric measures in older people

BMC Geriatrics

Table 4 Logistic regression models (Odds ratios and corresponding 95% confidence intervals (95%CI)) for the association of CKD and malnutrition: the presence of CKD (Model 1) predicted by nutritional and anthropometric variables, while malnutrition defined with MNA < 24 (Model 2) and malnutrition defined with albumin < 3.5 g/dL (Model 3) predicted by CKD stages. Each model was adjusted for age and sex (A), age, sex, concomitant diseases (diabetes mellitus, cancer, HF, CAD, CVD, COPD, metabolic syndrome) and country (B)
