Given that the relationship of symptoms over time was U-shaped, to facilitate model interpretation the data shown are for the first 7 months when the relationship was linear.
BL, baseline; CFB, change from baseline; SD, standard deviation derived from the random component of the model; SBP, systolic blood pressure; post wt, postdialysis weight.
*P < 0.05, **P < 0.01, ***P < 0.001.
