Figure 1. Distribution of low albumin concentrations among BMI values (N = 19).Note: A, area of low values; B, area of normal values; C, area of high values of the reference variable; D, areas of low values of the examining variable.

Figure 2. Distribution of low albumin concentrations among BMI values, (N = 89). Note: A, area of low values; B, area of normal values; C, area of high values of the reference variable; D, areas of low values of the examining variable.

Notes: Values of BMI less than 20 are coded 1, values 20 to 25 are marked as 2, and values higher than 25 are coded 3. Albumin levels less than 35 g/L are marked as 2.

Figure 4. Distribution of low URR among Kt/V values.Note: Normal values of URR <63.5%; A, area of low values; B, area of normal values; C, area of high values of the reference variable; D, areas of low values of the examining variable.
