A Cross-Sectional Analysis of Dietary Intake and Nutritional Status of Patients on Haemodialysis Maintenance Therapy in a Country of Sub-Saharan Africa

Table 4

The anthropometric markers (median) split by attainment of relevant reference ranges of dietary intakes (n = 42), dialysis adequacy (n = 50), and inflammation status (n = 62) for adults on haemodialysis in one Tanzanian centre.
