DAS28 was calculated using following formulas: DAS28-ESR = 0.56\*square root (sqrt) (TJC28) + 0.28\*sqrt(SJC28) + 0.70\*natural logarithm (ln) (ESR) + 0.014\*PtGA of disease activity; DAS28-CRP = 0.56\*sqrt(TJC28) + 0.28\*sqrt(SJC28) + 0.36\*ln(10\*CRP+1) + 0.014\*PtGA of disease activity. DAS28-ESR was adopted to calculate DAS28 if effective ESR data was available; otherwise DAS28-CRP was adopted to calculate DAS28. Total score range: 0-10, higher score=more disease activity.
