aAdjustment not performed since 24-hour SBP used as risk predictor. Adjustment for
bage, sex, diabetes mellitus and serum albumin (model A);
cmodel A plus UFV and log-transformed dialysis vintage (model B);
dmodel B plus 24-hour SBP (model C).
eModel C not calculated since proportional assumption violated for intradialytic SBP and PP.
