  1. Values are partial Pearson correlation coefficients with 95% confidence intervals (CI), adjusted for baseline values of the respective outcome and for sex, body mass index, and diabetes duration.
  2. CI, confidence interval; HbA1c, hemoglobin A1c; SD, standard deviation; TAR, time above range (> 180 mg/dL; >10.0 mmol/L); TBR, time below range (< 70 mg/dL; <3.9 mmol/L); TIR, time in range (70–180 mg/dL; 3.9–10.0 mmol/L).
