Summary

This trial aimed to see if heart rate variability biofeedback training (using a smartphone app) could reduce stress and anxiety in university students as well as or better than guided meditation. The study planned to enroll second- and third-year physiotherapy students and measure stress levels with standard questionnaires. However, the trial was withdrawn before any participants were enrolled, so no data were collected.

What this could mean

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

Active substance: Heart rate variability biofeedback training and guided meditation
What this could lead to: If it had worked, this could point toward simple, low-cost ways for students to manage stress and anxiety without medication.
What could go wrong: The trial was withdrawn before enrolling any participants, so no results are available. Even if conducted, the small, specific student group may not represent broader populations.
