Disability trajectory of two leg pain categories for low and high ODI scores. Disability measured with the Oswestry Disability Index (higher score indicates worse functioning). The red lines represent the group with radiating (radicular and non-radicular, n = 208) leg pain, the green lines represent the group with non-radiating low back pain (n = 137) The dashed lines represent the group with high ODI scores (> 22), the continuous lines represent the group with low ODI scores (≤ 22)
