Fig. 2. Kaplan-Meier survival curves for the three groups of subjects stratified by "nutrition-risk" as indicated. Subjects were stratified into the nutrition "high-risk" group if their albumin was less than 30 g/L or BMI was less than 19; and, "low-risk" group if albumin was equal to or greater than 35 g/L and BMI equal to or greater than 22. All others represented the "moderate-risk" group. (See text for details.)"
