Dialysis-Related Complications. The number of complications that a particular patient had during the intervention phase were divided by the number of his/her hemodialysis sessions at risk, i.e. all sessions during the intervention phase (panel a, N = 50 patients: N = 16 in CONV, N = 18 in UTR, N = 16 in UCR), or only the hemodialysis sessions with dry weight reduction during the intervention phase (panel b, N = 43 patients: N = 12 in CONV, N = 17 in UTR, N = 14 in UCR). The resulting percentages are depicted as boxplots including the means (shown as diamond). P-values shown above the boxplots for each complication outcome were derived from models for count data. Pairwise p-values are only shown if the global p-value was significant
