Summary

This study was designed to see if a short-term protein-calorie restriction diet before elective vein graft surgery is practical and how it affects the body. It planned to enroll adults scheduled for non-emergency lower extremity vein bypass surgery. However, the trial was withdrawn before any participants were enrolled, so no results are available.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Scandi-Shake (a dietary supplement used for protein-calorie restriction)
