INS and retinal disorder: In multivariate analysis integrating all significant covariates (in bold, in Tables 1 and 2), NDS scoring was still associated (r = 0.51, p<0.0001) with dp-ucMGP levels (β = 0.16, p = 0.025), height (β = 0.29, p<0.0001), HbA1c (β = 0.19, p = 0.006), insulin treatment (β = 0.19, p = 0.007), retinopathy treated by laser (β = 0.16, p = 0.015) and urinary albumin/creatinine ratio>3 mg/mmol (β = 0.14, p = 0.031) (Table 4).
