¹DER, dietary energy requirement.

²The constant energy intake provided to a given patient throughout the study, estimated on the basis of measured resting energy expenditure.

³Calculated on the basis of the sum of the constant energy intake of the maintenance hemodialysis patients and the changes in body calorie stores as determined by body fat and lean body mass (12).

⁴95% CI of the mean.
