Phase angle as a predictor of malnutrition, sarcopenia, and adverse clinical outcomes in hospitalized patients with ulcerative colitis

Figure 1 Receiver operating characteristic curves for malnutrition and sarcopenia in ulcerative colitis patients. A: Phase angle (PhA) values for malnutrition in females; B: PhA values for malnutrition in males; C: PhA values for sarcopenia in females; D: PhA values for sarcopenia in males; E: Different predictive indicators value for sarcopenia. PhA: Phase angle; PAB: Prealbumin; AUC: Area under the curve.
