200 Chapter 10 Supplementary Figure S4 Bland-Altman plot for difference (DAS28 – DAS-OST) using data of external validation cohort. External validation cohort consisted of 151 observations from the ACURA cohort. DAS-OST consisted of total OST-score, gender, ESR and VAS. Blue line= 0; Red line= mean of the difference; Red lines (dashed)= +/- 2SD of mean of the difference. Supplementary Figure S5 Bland-Altman plot for difference (DAS28 – DAS-OST(JC)) using data of external validation cohort. External validation cohort consisted of 151 observations from the ACURA cohort. DAS-OST(JC) consisted of √JC-OST, gender, ESR and VAS. Blue line= 0; Red line= mean of the difference; Red lines (dashed)= +/- 2SD of mean of the difference. Supplementary Figure S6 Bland-Altman plot for difference (DAS28 – DAS-OST with- out VAS) using data of external validation cohort. External validation cohort consisted of 151 observations from the ACURA cohort. DAS-OST without VAS consisted of total OST-score, gender and ESR. Blue line= 0; Red line= mean of the difference; Red line (dashed)= + 2SD of mean of the difference.
