In the predialysis cohort, the mean LVOT VTI was 28.05\u2009cm (95% confidence interval [CI], 26.55\u201329.55\u2009cm).

In the postdialysis cohort, the mean VTI was 30.31\u2009cm (95% CI, 28.92\u201331.69\u2009cm), and it increased to 34.91\u2009cm (95% CI, 33.11\u201336.72\u2009cm) after the passive leg raise. The \u0394 VTI values were 1.83% (95% CI, 0.12%\u20133.55%) in the predialysis group and 15.05% (95% CI, 12.76%\u201317.34%) in the postdialysis cohort.

In patients without congestive heart failure, the \u0394 VTI was 15.28% (95% CI, 12.25%\u201318.32%), whereas for those with congestive heart failure, the mean change was 14.63% (95% CI,
