Table 1. The parameters of clinical lab test of the study groups.
Parameters | DR(n=528) | DNR (n=515) | P-value |
---|---|---|---|
Age | 55±13.0 | 54±12.0 | 0.42 |
Male | 275 (52.08%) | 261 (50.68%) | 0.06 |
Body mass index (kg/m2) | 25.2±3.8 | 24.8±3.7 | 0.28 |
Smoking (N, %) | 195 (36.9) | 175 (34.0) | 0.32 |
Alcohol use (N, %) | 213 (40.34) | 198 (38.45) | 0.38 |
HbA1c (%) | 7.7±1.2 | 7.6±1.3 | 0.09 |
Blood urea (mgs%) (Mean±SD) | 31±11 | 28±8 | 0.06 |
Duration of diabetes (years) | 14±9 | 13±8 | 0.45 |
Blood pressure (mm Hg) | |||
Systolic | 138±9 | 139±8 | 0.36 |
Diastolic | 82±5 | 82±6 | 0.36 |
HbA1C means glycosylated hemoglobin. The data are means±SD or, for categorical variables, n or ratio. Comparisons between retinopathy groups are by unpaired Student's t-test or Χ2 test. P-values<0.05 are considered significant.
