Does Takayasu arteritis differ between children and adolescents? Insights from a Russian multicenter cohort

Figure 1 Gender distribution in the younger (< 10 years) and older (≥ 10 years) age groups. P = 0.016 (Fisher’s exact test).

Figure 2 Receiver operating characteristic curve for the number of surgical interventions as a predictor of early-onset Takayasu arteritis (≤ 10 years). Area under the curve = 0.877 (95%CI: 0.738-1.000).

Figure 3  Distribution of angiographic types (Hata classification[25]) in patients with childhood-onset Takayasu arteritis, stratified by age group.

Figure 4 Receiver operating characteristic curve for the logistic regression model predicting biologic disease-modifying antirheumatic drugs prescription. Area under the curve = 0.704 (95%CI: 0.589-0.820; P = 0.002). The optimal cut-off value (Youden index) was 0.396, corresponding to a sensitivity of 89.7% and a specificity of 46.2%.
