Figure 1 Relationship between protein supplied and consumed. Symbols are: (•) low protein; (▴) high protein. Kidney International 2000 58, 336-345DOI: (10.1046/j.1523-1755.2000.00171.x) Copyright © 2000 International Society of Nephrology Terms and Conditions
Figure 2 Absolute nitrogen balance increases linearly with increasing protein intake. Symbols are: (▪) low protein; (▴) high protein; r2 = 0.82. Kidney International 2000 58, 336-345DOI: (10.1046/j.1523-1755.2000.00171.x) Copyright © 2000 International Society of Nephrology Terms and Conditions
Figure 3 Scatterplot of dietary protein intake (DPI) versus normalized protein nitrogen appearance (nPNA). The regression line cuts the line of identity at a DPI of 0.75 g/kg/day (95% CI, 0.65 to 0.85 g/kg/day); nitrogen balance is likely to be negative below this level and positive above, given a constant calorie intake of 35 kCal/kg/day (r = 0.41; P = NS).
