INS and Insulin resistance: In comparison with the OW/OB controls, OW/OB patients with SJIA (n = 11) had higher insulin resistance index, as shown by median (IQR) homeostasis model assessment for insulin resistance (HOMA-IR) [2.6 (2.1–3.3) vs 1.5 (0.8–2.0), p = 0.001], and lower insulin sensitivity index as shown by median (IQR) whole-body insulin sensitivity index (WBISI) [3.7 (2.7–5.9) vs 5.4 (4.5–8.7), p = 0.024].
