High urea nitrogen: >7.1 mmol/l; hyperuricemia: uric acid >360 μmol/L; diabetes onset age refers to age at enrollment minus the duration of diabetes; when diabetes was newly diagnosed, the duration was recorded as 0 years, and the onset age was equal to the age at enrollment. The results of urine occult blood were stratified in routine urine examination, and the test results of “+”– “+ + + +” were defined as hematuria.
