Changes were calculated using pairwise measurements.

*δ values were calculated by taking the last available value minus index value, and was calculated for HbA1c (mmol/mol), eGFR (mL/min/1.73 m2), and weight (kg).

†Change (%) during the study period was calculated by dividing the δ value by the index value and multiplying by 100.

eGFR, estimated glomerular filtration rate; HbA1c: glycated hemoglobin.
