Note: Data of overall patients, patients with aTRH and non‐aTRH were presented as numbers and percentages, means and standard deviations, or median and interquartile range. KT/V, and PET were calculated by formulas mentioned before. PD, peritoneal dialysis; aTRH, apparent treatment‐resistant hypertension; BMI, body mass index; RRF, Residual renal function; SBP, systolic blood pressure; DBP, diastolic blood pressure; CAPD, continuous ambulatory peritoneal dialysis; UF, ultrafiltration; GLUC, glucose concentration; PET, peritoneal equilibration test, ESA, erythropoiesis‐stimulating agents.
PET type based on 1428 PD hypertensive patients including 863 nonaTRH patients and 565 aTRH patients.
P for comparisons between aTRH and nonaTRH patients by t‐test, Kruskal–Wallis test, or Chi‐squared tests for continuous and categorical variables, respectively.
