T1D patients with HbA1c >8% (>64 mmol/mol) had significantly higher CCL2 concentrations (241.0 (189.6–295.3) pg/mL) than controls (191.5 (158.0–254.7) pg/mL, p=0.033), whereas OB patients with BMI Z score >2 SD had significantly lower CXCL11 concentrations (6.6 (4.9–7.7) pg/mL) than controls (8.2 (6.9–11.3) pg/mL, p=0.018) (graphs not shown). This evidence concerns the gene CXCL11 and type 1 diabetes mellitus.
