4. 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).
