  1. Data are presented as mean ± SD. Overweight/obese controls without NAFL (controls, n = 7), overweight/obese with NAFL (NAFL, n = 15), patients with type 2 diabetes (T2D, n = 9), and GSD type 1a (GSD1a, n = 7). Age was significantly lower in GSD1a compared to control (p = 2.5 × 10−5), NAFL (p = 3.0 × 10−6), and T2D (p = 1.47 × 10−7). Plasma glucose was significantly lower in GSD1a compared to control (p = 0.011), NAFL (p = 5.6 × 10−5) and T2D (p = 1.44 × 10−10), and was significantly higher in T2D compared to control (p = 4.0 × 10−6) and NAFL (p = 6.0 × 10−6). Plasma insulin was significantly lower in GSD1a compared to NAFL (p = 3.4 × 10−5) and T2D (p = 0.006), and was significantly higher in NAFL compared to control (p = 0.048). Plasma TG was significantly higher in GSD1a compared to control (p = 3.0 × 10−6), NAFL (p = 1.33 × 10−4), and T2D (p = 2.0 × 10−6). ALT was significantly higher in NAFL compared to GSD1a (p = 0.011). AST was significantly higher in GSD1a compared to control (p = 0.006) and T2D (p = 0.017). Intrahepatic fat content was significantly higher in NAFL compared to control (p = 0.002) and GSD1a compared to control (p = 0.027). Bonferroni correction was used for post-hoc analyses.
  2. aSignificantly different from control.
  3. bSignificantly different from NAFL.
  4. cSignificantly different from T2D (Kruskal–Wallis, p <  0.05 for plasma insulin, plasma NEFA, ALT and intrahepatic fat content, and one-way ANOVA, p < 0.05 for all other parameters).
