Figure 3: (a) Four hour intradialytic systolic blood pressure in isothermic and 37°C temperature dialysis. The 4 h time averaged mean systolic blood pressure at isothermic and standard dialysis were 154 ± 1.7 and 157.2 ± 1.1 mmHg, respectively. The mean difference in systolic blood pressure between the groups was −3.4 and −3.1 mmHg, 95% confidence interval, P < 0.001. (b) Systolic blood pressure variability in isothermic and 37°C temperature dialysis. The standard deviation which is a measure of blood pressure variability was lower at isothermic dialysis. The mean of standard deviation of systolic blood pressure in isothermic and standard temperature dialysis were 13.8 ± 2 and 20.8 ± 6.2, respectively (P < 0.001)
