Table 4 Comparison (mean and SD) for Controls and for Cases. Data collected before vs after intervention (Cases) and for Controls (after 1 year free of AVF problems) and repeated within 8 weeks later for both groups. Also included are parametric and non-parametric comparisons between Controls first data and Cases before intervention
