Insights
The CONvective TRAnsport STudy (CONTRAST) found that on-line postdilution hemodiafiltration did not reduce mortality or cardiovascular events compared to low-flux hemodialysis. This review covers CONTRAST
Area of Science:
- Nephrology
- Cardiovascular Medicine
- Clinical Trials
Background:
- End-stage renal disease (ESRD) patients require renal replacement therapy.
- Hemodialysis is a common treatment, but cardiovascular complications remain high.
- Hemodiafiltration is an alternative treatment modality with theoretical benefits.
Purpose of the Study:
- To review and discuss knowledge from the CONvective TRAnsport STudy (CONTRAST) trial.
- To evaluate the efficacy of on-line postdilution hemodiafiltration versus low-flux hemodialysis.
- To analyze mortality and cardiovascular outcomes in ESRD patients.
Main Methods:
- The CONvective TRAnsport STudy (CONTRAST) was a large randomized controlled trial.
- It compared on-line postdilution hemodiafiltration with low-flux hemodialysis.
- The review synthesizes data on mortality, cardiovascular events, and subgroup analyses.
Main Results:
- CONTRAST did not demonstrate a significant reduction in mortality with hemodiafiltration.
- Cardiovascular events were not significantly different between the two treatment groups.
- Subgroup analyses provided further insights into treatment effects.
Conclusions:
- On-line postdilution hemodiafiltration did not show superiority over low-flux hemodialysis for major adverse outcomes in the CONTRAST trial.
- The findings contribute to understanding the role of hemodiafiltration in ESRD management.
- Further research may explore specific patient populations or alternative hemodiafiltration techniques.
Abstract:
The CONvective TRAnsport STudy (CONTRAST) is a large randomized controlled trial which compared on-line postdilution hemodiafiltration and low-flux hemodialysis in terms of mortality and cardiovascular events. This review summarizes and discusses currently available knowledge acquired by CONTRAST, including the main outcome, comparisons of hemodiafiltration to hemodialysis as well as studies performed in subgroups of CONTRAST.

Phase Contrast and Differential Interference Contrast Microscopy
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...
Real-World Application of Classical Conditioning
Higher-order, or second-order, conditioning occurs when a neutral stimulus becomes associated with an already established conditioned stimulus through repeated pairings. For instance, if a dog has been...
Crossover Experiments
Crossover designs are performed even with smaller sample sizes since the samples can act as their controls. These are better than simple randomized trials since patients are exposed to all the treatments.
Multiple Comparison Tests
It would be easy to compare two samples using a significance alpha level of 0.05. In other words, there is only one sample pair to be compared. However, it would be difficult to identify a significantly different sample if the number...
