Table 5. Alu repetitive elements genotypes and the severity of diabetic retinopathy.

Data are represented as percentages. The relationship of Alu repetitive elements genotype in patients with diabetic retinopathy and the severity of the disease. Frequencies and percentages of II, ID, and DD genotype in relation to the severity of retinopathy were calculated. A P-value of less than 0.05 was considered statistically significant.

Retinopathy Severity	II (n=30) %	ID (n=41) %	DD (n=9) %
Mild	26.7	29.3	11.1
Moderate	30.0	31.7	22.2
Severe	23.3	15.0	33.3
Proliferative	20.0	25.0	33.3
