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 annual progression rate of spinocerebellar ataxia using SARA scale change per year, stratified by SCA subtype and CAG repeat length

Each component has a specific meaning:

  • SARA scale change per year — The sara scale change per year recorded for the scenario being assessed.
  • Stratified by SCA subtype — The stratified by sca subtype recorded for the scenario being assessed.
  • CAG repeat length — The cag repeat length recorded for the scenario being assessed.

Note: Interpret the sca progression rate result against the thresholds and context described above.

How to Use

Enter the SARA scale change per year, stratified by SCA subtype, CAG repeat length for the scenario you are assessing. Estimate annual progression rate of spinocerebellar ataxia using SARA scale change per year, stratified by SCA subtype and CAG repeat length. Use the sca progression rate result to inform your calculation.
