Baseline Tender and Swollen Joint Counts
Placeholder: baseline exam counts tender and swollen joints.
- 28: Tender joint count (Placeholder baseline count)
- 20: Swollen joint count (Placeholder baseline count)
- 28: Joints assessed (Placeholder joint assessment set)
- 7: Core set measures (Placeholder ACR core measures)
Why baseline joint counts matter
Placeholder: baseline values anchor every later percent-improvement calculation.
Placeholder: accurate baseline scoring is essential for valid ACR response.
Post-Treatment Joint Count Improvement
Placeholder: therapy lowers tender and swollen joint counts over time.
- 0-100%: Joint slider control (Placeholder improvement range)
- ≥20%: ACR20 joint bar (Placeholder required reduction)
- ≥50%: ACR50 joint bar (Placeholder required reduction)
- ≥70%: ACR70 joint bar (Placeholder required reduction)
Tracking joint resolution visually
Placeholder: resolved joints fade from active red to inactive gray.
Placeholder: joint count improvement alone does not define ACR response.
Core Set Measure Improvements
Placeholder: five additional core measures track overall disease activity.
- 0-10: Patient global (Placeholder visual analog scale)
- 0-10: Physician global (Placeholder visual analog scale)
- 0-3: HAQ-DI (Placeholder disability index)
- mg/L: CRP (Placeholder inflammation marker)
Five core measures beyond joints
Placeholder: pain, global scores, disability and CRP all count too.
Placeholder: three of five core measures must improve for ACR credit.
Percentage Improvement Calculation
Placeholder: percent change from baseline drives the ACR decision.
- (base−cur)/base: Formula (Placeholder percent-change formula)
- live: Joint % improvement (Placeholder from slider 1)
- live: Core % improvement (Placeholder from slider 2)
- AND logic: Combined check (Placeholder both must clear bar)
Combining two percentage tracks
Placeholder: joint and core percentages are compared against the same cutoff.
Placeholder: both tracks must clear a threshold together for that ACR tier.
ACR20/50/70 Response Classification
Placeholder: final classification badges light as thresholds are crossed.
- Minor: ACR20 (Placeholder minimal response tier)
- Moderate: ACR50 (Placeholder moderate response tier)
- Major: ACR70 (Placeholder major response tier)
- <20%: Non-responder (Placeholder below ACR20 bar)
Reading the final response badge
Placeholder: the highest tier reached becomes the reported response.
Placeholder: ACR70 responders show the strongest treatment benefit.
