There were also significantly higher concentrations of IFN-γ in MHO (median, 1.76 pg/mL; range, 0.33–4.10 pg/mL; *P<0.0001) and T2D patients (median, 1.08 pg/mL; range, 0.36–3.43 pg/mL; *P<0.05) as compared to CTLs (median, 0.48 pg/mL; range, lower limit to 2.64 pg/mL). Here, IFNG is linked to type 2 diabetes mellitus.
