Overview of studied predictors of achieving DMARD-free remission. Data are presented from variables that were reported in >1 study, based on statistical significance obtained in regression analysis. If both univariable and multivariable regression was applied, the result of the multivariable regression was used. Presented are the absence (left panel) and presence of an association with achieving DFR over time (right panel), the number of studies is indicated per predictor, the total number of patients in these studies is plotted on the x-axis. The directionality of the effect is indicated in colours, green indicates an increased risk of achieving DFR, red indicates a decreased risk of achieving DFR. For symptom duration, no differentiation was made for analyses using this as continuous or categorical variable. BMI, body mass index; CRP, C reactive protein; DAS, Disease Activity Score; ESR, estimated sedimentation rate; HAQ, Health Assessment Questionnaire; RF, rheumatoid factor; SJC, swollen joint count.
