^a; ^b. CKD: diabetic kidney disease; UACR: urinary albumin : creatinine ratio; eGFR: estimated glomerular filtration rate; BMI: body mass index; SDNN: standard deviation of the RR interval; RMSSD: the root mean square difference of successive RR intervals; SDANN: standard deviation of the averaged normal RR intervals for all 5-minute segments; SDNN index: the mean of the standard deviations of all normal RR intervals for all 5-minute segments; LF: low frequency; HF: high frequency; LF/HF: the ratio of low-to-high-frequency power.
