OBJECTIVES: The aim of this study was to retrospectively investigate factors predicting a successful outcome after ozone chemonucleolysis (OCN) in patients with radicular pain and poor response to conservative treatments. METHODS: Univariable and multivariable logistic regression analysis was used to identify the predictors of good outcome after OCN. Good outcome was defined as 33% Oswestry Disability Index (ODI) reduction (model 1) or 13-point ODI improvement (model 2) at 1 month after OCN. RESULTS: Two hundred seventy-three patients were analyzed. A significant pain reduction (pre-operative Numerical Rating Scale [NRS] 6.7 ± 1.5, postoperative NRS 2.6 ± 2.2, P
