Note: SE = Standard Error; BMI = Body Mass Index; MNA-SF = Mini Nutritional Assessment Short-form; TMD = Texture-Modified Diet; ONS = Oral Nutritional Supplement; Multiple linear regression analysis was used: Energy intake ~ Intercept + Age + Gender + Level of care + Length of stay + Mobility level + Feeding assistance + TMD level + Weight + BMI + MNA-SF + consumption of ONS; MNA-SF ~ Intercept + Age + Male + Level of care + Length of stay + Mobility level + Feeding assistance + TMD level + Weight + BMI + consumption of ONS; a Reference category = Female; b Reference category = Hospital level; c Reference category = Mobile; d Reference category = No feeding assistance; e Reference category = Level 4—pureed diet; f Reference category = No supplements.
