Bioimpedance-assessed volume overload predicts interdialytic hypertension and disrupted circadian blood pressure rhythm in maintenance hemodialysis patients
Fig 2
Correlation analysis of interdialytic blood pressure with clinical, laboratory, and volume status indicators.
Scatter plots showing the correlation between 44h SBP and iPTH (A), Post-HD Scr (B), Post-HD BUN (C), Kt/V (D), URR (E), OH (F), ECW/TBW (G), ECW/ICW (H); 44h DBP with age (I), iPTH (J), Post-HD Scr (K), OH (L). p < 0.05 was considered statistically significant. Abbreviations: 44h SBP, 44-hour mean systolic blood pressure; 44h DBP, 44-hour mean diastolic blood pressure; iPTH, serum intact parathyroid hormone; Post-HD Scr, post-dialysis serum creatinine; Post-HD BUN, post-dialysis serum urea nitrogen; Kt/V, Calculate dialyzer urea clearance×time/distribution volume; URR, urea reduction ratio; TBW, total body water; ECW, extracellular water; ICW, intracellular water; OH, overhydration.
