Methodology · worked example, guidelines & full notes
ESR and CRP versions are not interchangeable.
When to use
Treat-to-target management of rheumatoid arthritis.
How it works
0.56·√TJC28 + 0.28·√SJC28 + 0.70·ln(ESR) + 0.014·global health. < 2.6 remission, > 5.1 high.
Key points
- ESR and CRP versions are not interchangeable.
- Track the same version over time.
- Drives escalation/de-escalation of therapy.

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.
| Tender joint count (0–28) | 5 |
|---|---|
| Swollen joint count (0–28) | 3 |
| ESR | 30 mm/h |
| Patient global health (0–100) | 40 mm |
