| Measure | Time frame |
|---|---|
| he primary outcome measure is the repeatability coefficient defined as 1.96 x *2 x within-subject SD. The within-subject standard deviation is derived from the variance calculated using a one-way ANOVA of the dataset, where the data pairs are always 38 1st, 38 2nd and 38 3rd dialyses of the week. We aim for a repeatability coefficient of 6-7 ml/kg, which corresponds to a measurement error of 10%. | — |
