Spinal radiographic progression in patients with high risk of progression (patients already treated with TNFi, but not reaching an ASDAS ≤ 2.1 at the beginning of each radiographic interval). Cumulative probability plot of 2-year progression in the modified Stoke Ankylosing Spondylitis Spinal Score (mSASSS; range 0–72), illustrating the change in total (cervical + lumbar) mSASSS values from baseline of each individual radiographic interval to 2 years (grey). The mSASSS values for the cervical and lumbar spinal segments (range 0–36) are shown in blue and green, respectively. Radiographic progression was defined as an increase in total mSASSS of ≥ 2 units in 2 years and an increase of ≥ 1 unit if only the cervical or lumbar segments of the spine were considered (dotted lines)
