a Comparison of symptom preservation in patients ≤ 65 versus > 65 years of age using Kaplan-Meier analysis. Age did not significantly influence symptom deterioration. b Comparison of symptom preservation in patients with versus without vertebral body slip using Kaplan-Meier analysis. Vertebral body slip (≥ 3 mm) did not significantly influence symptom deterioration. c Comparison of symptom preservation in patients with versus without scoliosis using Kaplan-Meier analysis. Scoliosis (Cobb angle ≥ 10°) did not significantly influence symptom deterioration. d Comparison of symptom preservation in patients with the presence or absence of redundant nerve roots of the cauda equina Kaplan-Meier analysis. Redundant nerve roots of the cauda equina did not significantly influence symptom deterioration
