DR: diabetic retinopathy; BMI: body mass index; LDL: low density lipoprotein; HDL: high density lipoprotein; eGFRcr: estimated glomerular filtration rate by serum creatinine; eGFRcys: estimated glomerular filtration rate by serum cystatin C; ACR: albumin to creatinine ratio. Data presented are proportions or means and standard deviation as appropriate for the variable. value represents difference in characteristics by moderate DR status by analysis of variance or the chi-square test.
