We conducted limited posthoc analyses and did not find significant differences in mean GTT when the threshold for low albumin was < 2.5 mg/dL (n = 26) or < 2.0 mg/dL (n = 7) or when we compared the mean GTT for patients with CKD (Stage 4 or 5) (29 minutes) to those without CKD (26 minutes). Here, ALB is linked to chronic kidney disease.
