Improving disability (HR=0.62, p=0.039) and disease-modifying therapy exposure (HR=0.71, p=0.007) were associated with a lower risk. Recent cerebral magnetic resonance imaging activity, evidence of spinal cord lesions and oligoclonal bands in the cerebrospinal fluid were not associated with the risk of conversion. Conclusion:Risk of secondary progressive multiple sclerosis increases with age, duration of illness and worsening disability and decreases with improving disability. Therapy may delay the onset of secondary progression.]]> Wed 24 May 2023 12:22:34 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:36719 Mon 24 Aug 2020 10:45:35 AEST ]]>
