Mean SBP changes from baseline to 4 weeks (4w) and from baseline to 8 weeks (8w) in the ultrafiltration (UF) group minus changes from baseline to 4 weeks and from baseline to 8 weeks in the control group. The error bars are the 95% confidence intervals of the means. When the bars transect the zero line, then the changes from baseline are not statistically significant. a The paired data shown are those detailed in table 2. b All available data. Predialysis (PreD) BP is insensitive in detecting change. PostD = Postdialysis; ABP = ambulatory BP.
