Time in target range (TTR) for systolic blood pressure (SBP) and hemoglobin A1c (HbA1c) integrates information about average and variability of levels over time. Their impact on kidney outcomes has not been fully evaluated. This study investigated the association of HbA1c-TTR and SBP-TTR, individually and jointly, with kidney outcomes among patients with type 2 diabetes and hypertension.
