What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.

Summary

This study compares two minimally invasive procedures for people with low back pain that radiates into the leg (radiculopathy) and hasn't improved with conservative care. One treatment injects ozone gas into the spinal disc, while the other uses pulsed radiofrequency to deliver electrical pulses to nerves. Researchers will track pain levels and disability over six months to see which approach offers more lasting relief and fewer complications.

What this could mean

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

Active substance
Ozone therapy (intradiscal ozone injection) and pulsed radiofrequency (a minimally invasive procedure using electrical pulses)
What this could lead to
If one method proves more effective, it could become the preferred first-line minimally invasive option for stubborn low back and leg pain, helping more people avoid surgery.
What could go wrong
This is a small, retrospective study, not a randomized trial, so results may be influenced by bias or chance. Also, both procedures carry risks like temporary pain or discomfort, and the benefit may not last beyond six months.
