Figure 1From: Comparison of remission criteria in a tumour necrosis factor inhibitor treated rheumatoid arthritis longitudinal cohort: patient global health is a confounderCharacteristics of disease activity score based on 28 joints and Boolean remission groups. (A) Percentage of patients in disease activity score based on 28 joints (DAS28) remission versus Boolean remission. 3 m, 6 m and 12 m: 3 months, 6 months and 12 months post tumour necrosis factor inhibitor therapy. (B) The 1-year four-variable disease activity score (DAS28(4v)) was higher for patients who failed Boolean remission due to just one subcriterion being ≤1, but disease activity did not differ from Boolean remission calculated with the three-variable formula (DAS28(3v)). This explains that significant differences in disease activity resulted mainly in higher patient global health. (C) The DAS28(4v) was higher in the only DAS28 remission group, but disease activity did not differ from Boolean remission patients calculating with the DAS28(3v). This explains that significant differences in disease activity resulted mainly in higher patient global health. ***P <0.0001. SD, standard deviation.Back to article page
