Clinical Characteristics, Anti-hyperglycaemic Treatment Pattern and Target Attainment of Type 2 Diabetes Mellitus Patients in Older Population With or Without Albuminuria in China

Renal Function Level of Patients Measured by Albuminuria

The renal function level of patients was measured by albuminuria into following categories - normal, micro-albuminuria, macro-albuminuria and missing data. Albuminuria was measured using either as a random spot urine sample, a 24-h urine sample, or a timed urine sample. Normal was defined as \< 30 mg/g, \<30 mg/24h, and \< 20 μg/min with the random spot urine sample, the 24-h urine sample, and the timed urine sample, respectively. Micro-albuminuria was defined as 30 - 300 mg/g, 30 - 300 mg/24h, and 20 - 200 μg/min with the random spot urine sample, the 24-h urine sample, and the timed urine sample, respectively. Macro-albuminuria was defined as \>300 mg/g, \>300 mg/24h, and \>200 μg/min with the random spot urine sample, the 24-h urine sample, and the timed urine sample, respectively.

Renal Function Level of Patients Measured by Chronic Kidney Disease (CKD) Stage

The renal function level of patients was measured by CKD into following categories - eGFR ≥ 60 milliLitre/minute/1.73 meter \^ 2 (mL/min/1.73m\^2), eGFR \< 60 mL/min/1.73m\^2 and missing data.
