Association between Serum Bilirubin and Estimated Glomerular Filtration Rate among Diabetic Patients

Table 1

Characteristics of various risk factors of the subjects.

Characteristic ()	Value
Gender male (%)	45.2
Age (years)	79 ± 10
Body mass index^† (kg/m^2)	21.5 ± 3.9
Smoking status^‡ (%)	74.7/2.2/9.8/13.4
Systolic blood pressure (mmHg)	137 ± 27
Diastolic blood pressure (mmHg)	75 ± 15
Antihypertensive medication (%)	56.2
Triglycerides (mg/dL)	82 (61–114)
HDL cholesterol (mg/dL)	55 ± 17
LDL cholesterol (mg/dL)	104 ± 35
Antidyslipidemic medication (%)	8.4
Fasting blood glucose (mg/dL)	151 (132–183)
Antidiabetic medication (%)	43.6
Serum uric acid (mg/dL)	5.5 ± 2.1
Serum creatinine (mg/dL)	1.1 ± 0.9
eGFR (mL/min/1.73 m^2)	56.0 ± 20.2
CKD stage (1 + 2/3a/3b/4), %	51.5/21.2/14.5/12.8

Cardiovascular disease (%)	40.1

Data are presented as means ± standard deviation. HDL: high-density lipoprotein; LDL: low-density lipoprotein; eGFR: estimated glomerular filtration rate. ^†Body mass index was calculated using weight in kilograms divided by the square of the height in meters. ^‡Smoking status: daily consumption (pack) × duration of smoking (year) {never, light (<20 pack⋅year), moderate (20–39 pack⋅year), and heavy (≥40 pack⋅year)}. Data for triglycerides, fasting plasma glucose, and serum bilirubin were skewed and are presented as median (interquartile range) values.
