Central arteriolar equivalent central venular were estimated via computer-based methods; overall magnitude speed narrowing quantified as cumulative average slope, respectively. Median regression models measures status, adjusted for duration. Interactions HbA1c, proliferative retinopathy white matter hyperintensities assessed.Results:Compared parti...
