Erratum
After publication of [1], it has come to our attention that the samples used for the MMPs and TIMP-1 measurements were serum samples instead of plasma samples. Therefore,
1. Plasma levels of MMPs and TIMP-1 in the title, abstract, methods, results and discussion section should read serum levels; and
2. In the discussion section, the following paragraph: “We did not find a significant association of plasma MMPs or TIMP-1 levels with non-proliferative retinopathy. This is in contrast with the results of the study of Jacqueminet et al [10], in which increased serum MMP-9 levels were shown in patients with type 1 diabetes with minimal to moderate retinopathy (n=14) compared to diabetic patients without retinopathy and non-diabetic controls. Possibly the serum measurement does not truly reflect the circulating concentration of MMPs and TIMPs compared to the plasma measurement [35]” should read “We did not find a significant association of serum MMPs or TIMP-1 levels with non-proliferative retinopathy. This is in contrast with the results of the study of Jacqueminet et al [10], in which increased serum MMP-9 levels were shown in patients with type 1 diabetes with minimal to moderate retinopathy (n=14) compared to diabetic patients without retinopathy and non-diabetic controls.”
We apologize for any inconveniece.
