Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Grade | III — Drowsy, confused, mild focal deficit |
|---|
→Hunt-Hess3/5
- Note：Higher grades correlate with worse survival and outcome.
| Grade | I — Asymptomatic or mild headache |
|---|
→Hunt-Hess1/5
- Note：Higher grades correlate with worse survival and outcome.
