Limitations
There were a few limitations in this study. This was a single-center study based on a relatively small group of patients. The sample size may not be large enough to generalize the results. Patients on hemodialysis were also excluded; therefore, the validity of the results for different populations is potentially limited. We could not confirm EFT measured by magnetic resonance and computed tomography imaging methods. Another limitation was that the association with APV and PWV was not evaluated. A large randomized clinical trial is needed to provide strength to present study findings.
