Descriptive methods and statistical tests will be used to examine the trajectories of outcome measures for patients in the comparator and intervention groups. The area under the curve (AUC) will be calculated for each trajectory during the period that the patient is participating to create a summary score. Analysis of covariance (ANCOVA) will be used as the method of analysis to compare AUC scores of outcomes of both groups while controlling for within- and between-group differences, such as comorbidities, gender, age and dialysis type.
