TTR and peritonitis: Oppositely, according to the results of Kaplan-Meier analysis in Fig. 3, patients with a low prealbumin level (serum prealbumin ≤32.5 mg/dL: blue line) exhibit a significantly higher peritonitis rate than those with a high serum prealbumin level (serum prealbumin > 32.5 mg/dL: violet line) (log-rank test, p <  0.001).
