RNN, recurrent neural network; MLP, multilayer perceptron; LightGBM, Light Gradient Boosting Machine; LR, logistic regression; IDH-1, intradialytic hypotension defined as nadir systolic BP <90 mm Hg; IDH-2, intradialytic hypotension defined as decrease in systolic BP ≥20 mm Hg and/or decrease in mean arterial pressure ≥10 mm Hg on the basis of BP at initial time point; IDH-3, intradialytic hypotension defined as decrease in systolic BP ≥20 mm Hg and/or decrease in mean arterial pressure ≥10 mm Hg on the basis of BP at prediction time point.
