From: Predicting factors of intradialytic hypotension in the last half of hemodialysis therapy
Receiver operating characteristic (ROC) curve analysis to identify the cutoff points of the serum level of sodium and rate of decrease (start to the midpoint) of the peak E-velocity as predictors of IDH in the latter half of a hemodialysis session. a The ROC curve analysis revealed a cutoff value of 137 mEq/L and area under the curve of 0.79 for the serum sodium level, with a sensitivity of 69% and specificity of 64% for predicting IDH. b The ROC analysis revealed a cutoff value of 0.295 and area under the curve of 0.71 for the rate of decrease of the peak E-velocity, with a sensitivity of 73% and a specificity of 71% for predicting IDH. IHD, intradialytic hypotension; AUC, area under the curve
