prednisolone is a version of corticosteroids. It has the equivalency of prednisone it just metabolizes differently. Dexamethasone is the strongest at about 5.25 to 1 strength of prednisone. Prednisone is 5 times stronger than hydrocortisone. So I would think there are many that have gotten off the steroids without a relapse. I was able to get off in 6 months. I did have 1 relapse but I treated it with a 5 day pack and stopped. I have been off 3 years. I dont know about the 50% statistic. That seems high.
