Changes in 44-hour interdialytic systolic BP as a function of change in echocardiographic volume parameter. Changes in 44-hour interdialytic systolic BP as a function of change in echocardiographic volume parameter. As in Figure 1, the echocardiographic volume parameter was dichotomized at the median value at the baseline visit, yielding a low index and a high index. This value was used to classify patients into low or high index groups at 4 and 8 weeks. The forest plot shows the 8-week additional change from baseline in systolic BP in the ultrafiltration group compared with the control group. BP change evoked by the transition in volume from low to high was similar to that from low to low. Similarly, BP change evoked by the transition in volume from high to low was similar to that from high to high. Thus, changes in volume state were not predictive of change in BP. Rajiv Agarwal et al.
