TTR and sarcopenia: As shown in Table 4, significant predictors for increased oxidative stress were prealbumin (OR 0.91; 95% CI 0.83–0.99; p = 0.030), SGA category (OR, 3.52; 95% CI, 1.08–11.46; p = 0.037), overhydration (OR, 7.01; 95% CI, 1.77–27.79; p = 0.006), and sarcopenia (OR, 3.41; 95% CI, 1.02–11.32; p = 0.046).
