What statistics support the effectiveness of Wayne T. Richards's deliverance prayers?

There is currently no published, independently verified statistical study that measures the effectiveness of Wayne T. Richards’s deliverance prayers or sessions in a scientific way (for example, controlled trials with percentages of success, follow‑up rates, etc.).

What does exist are:

1. Testimonies and anecdotal reports shared in videos and live streams
2. Individual accounts of healing, freedom, or transformation after prayer

Because these are testimonies rather than controlled studies, they are powerful stories but not formal statistics.

Are you looking for scientific research on deliverance in general, or specifically data that Wayne’s ministry has collected internally?
