SPMS Progression Rate and Transition Risk Estimator

Estimate the probability of transitioning from relapsing-remitting to secondary progressive multiple sclerosis using age, EDSS at diagnosis, relapse rate, and incomplete recovery variables from the MSBase registry.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Estimate the probability of transitioning from relapsing-remitting to secondary progressive multiple sclerosis using age, EDSS at diagnosis, relapse rate, and incomplete recovery variables from the MSBase registry

Each component has a specific meaning:

  • Relapsing-remitting — The relapsing-remitting recorded for the scenario being assessed.

Note: Interpret the spms transition risk result against the thresholds and context described above.

How to Use

Enter the relapsing-remitting for the scenario you are assessing. Estimate the probability of transitioning from relapsing-remitting to secondary progressive multiple sclerosis using age, EDSS at diagnosis, relapse rate, and incomplete recovery variables from the MSBase registry. Use the spms transition risk result to inform your calculation.
