Self-assessed patient global assessment of disease activity on a visual analog scale was not included while calculating DAS28-ESR3 and DAS28-CRP3 and was included for DAS28-ESR4 and DAS28-CRP4. Numbers in boldface indicate agreement between the 2 scores. Numbers in italics are the numbers of patients for whom disease activity would be “underestimated” if DAS28-CRP were used instead of DAS28-ESR. DAS28: 28-joint Disease Activity Score; ESR: erythrocyte sedimentation rate by Westergren method; CRP: C-reactive protein.
