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

Classify subarachnoid hemorrhage severity using the World Federation of Neurosurgical Societies scale based on GCS and motor deficits

Each component has a specific meaning:

  • World Federation of Neurosurgical Societies scale based on GCS — The world federation of neurosurgical societies scale based on gcs recorded for the scenario being assessed.
  • Motor deficits — The motor deficits recorded for the scenario being assessed.

Note: Interpret the wfns sah grade result against the thresholds and context described above.
